Is mocking Jews allowed in this subreddit?
Are you suggesting that mocking Jews be allowed in this subreddit because it is allowed in the US constitution?
We are not discussing about free speech in general, for an example, pro-dog posts and other similar posts are banned here.
There are other subreddits where they allow such things, this is not a subreddit about mocking religions, all I am suggesting is that using the term "dog of peace" with pitbull in analogy to "religion of peace" with sarcastic reference to Islam being violent is Islamophobic and it compares dogs to Islam.
Just read this rule:
Bigotry is not allowed
Comments or posts intended to demean a group (such as a religion, race, gender, or political affiliation), expressions of bigotry and prejudice, and the pejorative use of slurs are disallowed.
This is what we are discussing, not the US constitution and freedom of speech, and censoreship. This rule shows that posts here are censored, and many posts are.
