I've been on Gab since its inception - the only type of comments/users that get booted are those who engage in illegal speech. Illegal speech != distasteful/hateful/politically-charged/racist/sexist/divisive/etc.

Is hate speech right? In most cases, probably not unless you're saying things like "f..k all pedophiles who rape children", then it's righteously motivated. Is it legal? Yes. This is a very important distinction and what gives the USA its unique character and distinguishing trait among ALL other nations who do not have these types of freedoms codified in their constitutions...in fact, in many countries you'd be sacked quietly for saying the "wrong" thing - where "wrong" is defined by whomever happens to be in power (e.g. Russia, China come to mind)
