Sorry guy, but freedom of speech doesn't apply in the private sector, only the public. Particularly on the internet. Your constitutional rights, that you may or may not be fully familiar with (in this case, I'm leaning toward the latter), do not apply to certain places.

Other countries, websites, television, radio, magazines, etc. Are in some cases not at all covered, in many cases, covered except for certain circumstances, and in exceedingly few, covered completely.

You can't go blathering profanity on the radio, the FCC will have your nuts, you can't practice your first amendment rights on American soil within 200 feet of certain establishments, etc.

This is especially true on the internet. The community has no reason to respect whatever you think you have the right to say. If it doesn't belong, this community isn't yours, and just deal with it being deleted. Period.

There's no rallying, there's no protesting it, and there's absolutely nothing going to change the mind of those in charge of the community.
