"it appears that you are trying extremely hard to assert that you are straight by using such terms as 'bird' and 'geezer'"
That's the way i speak, and have spoken since i was 14/15 years old. It has nothing to do with masculinity, more with vinacular.
"How do you think the women that you are referring to as 'birds' feel?"
A word such as 'birds' is merely a slang term, much like 'bloke' is. It is not used in a derogatory manner in any way, shape, or form, by anyone - in the same way as 'bloke' is not derogatory in any way.
