No offense, but the internet is not a place for people who take offense easily. It’s a tough, wild west kind of place. It created (or at least evolved) the word “hater” to put the onus on those making critical comments. Self appointed sheriffs are not embraced, nor are those who attempt to grade each post according to their own standards. If you don’t like a particular post, I can respect that, but passing over posts you don’t like is the internet way or else there would be literally millions of posts debating the merits of each and every post. There still is a first amendment.
This is private property and the first amendment has no relevance to what is posted here. As I've already noted, there was a time, not that long ago that ebonics mockery wasn't tolerated here by the owner and his representatives.
Maybe policy has changed or the mods can't keep up with it all. The first amendment has nothing to do with it.
