Homosexuality? What? My example was about trans individuals, not homosexuals.
And even then yes, it's just an opinion. If you get intimidated by an opinion that's your problem, not the problem of the speaker. As long as the opinion wasn't specifically designed to intimidate you ("I think being trans is a mental illness." vs. "You trans people are mentally ill, we will deal with you!!") there is absolutely no problem with that kind of opinion.
If there were a problem whenever whenever some individuals decide that they feel intimidated literally anything would be off-limits.
That's just idiotic. As I have already said, a person can "feel" threatened by things that aren't designed to threaten them. "I don't like homosexuality." for example is merely the expression of a person who - while I disagree with his view - has every right in the world to give his opinion, yet it gets people up in arms and assert tons of other meaning behind it which then makes them feel threatened with violence.
