It's not even clear what you're suggesting we do, besides cosmetically removing the "Your freedom of speech does not apply here" statement from the rules. That statement is really there as a reminder that this is a privately owned forum and claims that your freedom of speech are being violated do not apply to actions taken on the site. This is true on every such website, we just happen to say so explicitly.
In terms of what we actually do, we've already told you that we allow nearly all political opinions, except for ones that are outright discriminatory or advocate physical violence. If you're here to discuss politics, this should be all you need. Rules on inappropriate content and language are much stricter, but this is not a matter of stifling opinions. Likewise with flaming and trolling, where strict enforcement is needed to keep the site a civil place to discuss.
I encourage you to take the time to get to know the community before trying to offer more suggestions or criticisms. There's plenty to suggest or criticize, as with any site - you can scroll through Site Feedback and read all about it - but you do need to get to know the site in order to offer meaningful feedback.
