Im a bit late here but I've been thinking about this one for some time so Ill try and explain this one as best I can Lost Soul.
I am a major proponent of free speech and, like you, I do not like censorship. However, there are a number of reasons why censorship is actually fairly productive and necessary on RF.
Firstly, it is important to remember that RF is a privately owned site. Without Rex and Todd, we wouldn't even have this site available to us. Now firstly this obviously means anybody who uses this site is immediately indebted to their goodwill (or that is the way I feel about it at any rate) and so paying the small compromise of sacrificing one's own personal beliefs about censorship for the smooth running of this site does not seem like a lot. Secondly, it does mean that they are responsible for this site. If we allowed discussion of illegal activity for example, then RF might be closed down and Todd would have a legal responsibility to report the action to the authorities which is not exactly a pleasant position to be put in.
Additionally, this isn't just a free for all discussion site. This is a religious forum and with that comes a certain amount of structure that needs to be maintained in order for productive debate to be achieved. If flame wars or trolls were allowed to continue all the time then this would be near impossible.
Therefore, if a person has beliefs that are not congruent with homosexuality then that is fine. The expression of such beliefs is also fine as is debate of them if posted in the correct forum. However, at the same time, hateful and derrogatory language is not allowed and so any expression must avoid these pitfalls. Unfortunately, the vast majority of people who hate homosexuals also believe homosexuality to be wrong. However, this statistical likelihood should not be used as evidence that RF discriminates against anti-homosexual views. It just seems intuitive that you will get more hateful language in anti-homosexual views than pro-homosexual views and therefore a gap in censorship will occur accordingly.
