We all speak and post from our own experience. It is not specific to crossdressing or gay people. Join a forum on cars or boats and it's the same thing.
We also have our individual likes and dislikes. We don't drop those when we strap on a pair of boobs. Some of these likes and dislikes we should probably keep to ourselves but sometimes people push us until we can't keep them inside any more.
And, as a couple members pointed out, there are some real "bullies" on this forum (see Traci G's post above). People who are going to come back and harass you if you post something they don't agree with. This goes back to my first statement about posting from your own experience without any understanding of the fact that others may have different experiences.
