God yes, especially if you are from the oppressed minority group in question but don't have the exact same opinion and are afraid of voicing it because you are afraid you will get dogpiled, anyway. No group holds a monolithic view and there will always be disagreements (eg. I have Asperger's Syndrome and I don't like being called 'differently-abled'. I find it a very vague term. I mean, if other people with Asperger's want to be called that, okay, that's their preference and I shouldn't silence them, but personally, I don't like to be called that).
