Should they censor this site or should we be able to keep our freedom of free speech?

Yes, IMHO I am glad there are moderators on this site. I'd expect them to take out blatantly inappropriate stuff. That stuff is just a waste of time.

By the way, your question was worded inappropriately. You asked two questions which makes it hard to vote on this.

what is appropriate? "smelling farts" one mans funny comment to another its crud. Just like everything one will like it one will not but it should be free to ask any question or any comment. I did word it bad sorry.

The comments that are the most vagrant are the ones that deserve the most protection. Every opinion deserves the right to be expressed, as long as it has caused no tangible harm on others (ex. like specifically threatening murder to an individual).
