You need to get over yourself and understand that this is just a friendly “trash talking” discussion. I think you may have taken it a bit to seriously. It’s just beer, nothing more.
But making it personal and telling me I need to “hand over my guy card and wave a rainbow flag” is uncalled for...and a not something you would expect anyone to tolerate.
Maybe I insulted your beer, but I never insulted you. Why are you insulting me?
