Back on topic?
No one (the government, AB etc) suppresses anyone's opinion - they draw a line on what is considered 'hate-speech'. You can hold whatever opinion you want, but expressing such opinions in public may generate genuine concern for some members of the community. You can agree or disagree that these rather arbitary lines are draw correctly and if you disagree there are ways of getting these laws changed (but posting on an insignificant forum in an insignificant corner of the internet is not one of them).
This type of Daily Mail-esque post falls into the same bracket as all the 'elf and safety gone mad' nonsense which gets some peoples backs up, it's simply a question of recognising the intent and wording a response that doesn't fall foul of the rules. If someone finds themself unable to do that, perhaps they should refrain from expressing opinions until they have improved their vocabulary and thought processes to a degree where they can voice their opinions in a civilised manner.
This is the type of ruling which will be railed against by those in the majority but has been shown time and time again to be necessary to protect those in the minority. Personally, I think the line is necessary, but is currently in the wrong place - however, outside of a few illiterate, ill thought out and incendiary posts I haven't seen anything reasonable censored.
