Anyone who knocks on my door and says: "Here is my thing! Look at it! I want you to embrace it!" is being rude. That's just my own personal opinion. I would not call it aggressive unless it was done before 10am though, although we'd probably disagree on what "aggressive" really means
To me, "aggressive" means not leaving when told "No" or "I'm not interested." And yes, it's also aggressive to get someone out of bed at 8 am on a Saturday (or any other day of the week).
"Aggressive" would also apply to the would-be doorknocker who buzzed several suites in my building awhile ago. She refused to leave when told "no/not interested" and continued arguing. The manager told me I wasn't the only person to complain about it, and he's in full agreement that such people are not to be allowed to get in here and harass people. It's an actual rule here that we're not supposed to buzz such people into the building (nor are we supposed to allow salespeople/solicitors to come in).
You could also be a strong atheist who truly 100% believes that gods don't exist, someone who meets with other similar atheists, have established a church within which they spread their message, meet on a regular basis, and have a tax free status.
Every atheist I've been acquainted with in RL and many who post on the CBC.ca website are of the view that churches should not be tax-exempt... particularly when they want the say over what laws politicians do and don't pass.
As I understand it, an atheist believes there is no God. (IMHO, that requires a lot of faith.) An agnostic doesn't believe one way or the other.
Why should it require faith?
I think most atheists don't really care about god; they are more worried about 1) the prospect of religion gaining ground in the world and 2) keeping JW et al off their doorstep. They want reason and scientific methodology to be the only accepted path of discovery for what is true.
There are two religion-based political issues going on right now in my province. One is GSAs (Gay-Straight Alliances) in schools. The government has threatened to pull funding from any publicly-funded faith-based school that refuses to allow these. The parents who oppose GSAs are livid that these alliances (school clubs) exist to provide a safe zone for LGBTQ students who may not have come out to their parents. A bill was passed that makes it illegal for schools to inform the parents if their child has joined a GSA.
The government gave these schools a generous amount of time to get their policies in step with the legislation. Many did, but some haven't, so they are about to lose their funding. Next year's election may see the government being formed by the United Conservative Party, which is led by a former Reformacon politician who was a cabinet minister under Stephen Harper (the PM we tossed out in 2015). Jason Kenney is a bigot who sees no need for protections for certain minorities in the population, and would certainly write legislation to repeal the laws pertaining to GSAs. He doesn't give a damn that kids should not be forcibly outed to parents who may kick them out into the street if their religious beliefs tell them that a gay son or daughter is some kind of abomination or needs to be forcibly "cured".
The other issue is MAiD (Medical Assistance in Death). Some nursing homes are run by a Christian organization called Covenant House (my dad is in one of them; it was the only L4 placement open here in Red Deer, so I had no choice but to send him there unless I wanted to leave him in a city I can't get to, for visiting or conferences). Some of these places would force residents who wanted medical assistance in dying to go elsewhere to receive assessments, keep appointments, or even to sign papers. The provincial health minister seemed in no great hurry to force these institutions to follow the laws that prohibit such restrictions.
These institutions receive government funding. They are not following the laws, citing religious reasons. Alberta is rife with ways in which the Catholic Church is allowed to do an end run around the Charter of Rights, and it has resulted in teachers losing jobs, nurses losing jobs, patients treated with either minimal care or being turned away, and people who qualify for physician-assisted death being forced to be wheeled off the premises into a bus shelter or park or onto the sidewalk just to sign a piece of paper.
That's not an ethical way to run a care facility.
To be honest, I've never met anyone that was all that concerned about people on their doorstep, other than Valka. At my gf's house we get about five times as many solar power or home security sales types as we get from all religions combined...and they are usually more rude and less attractive.
I'm not the one in my old neighborhood with a sign on the screen door that reads "We shoot every fifth JW. The fourth one just left in a hurry."
I doubt they're seriously engaging in murdering JWs. But it is an expression of antipathy toward them and an indication that when they arrive at the door and read it, they should immediately leave without ringing the bell, knocking on the door, or attempting to engage the residents in any way.
