Basically, if I tell you something, or look like something, and you make an assumption based on what I told you or how I look, don’t blame me when your assumption turns out not to be true. I cannot possibly write my entire life’s story in all its nuance and detail every time I communicate with somebody. It’s not possible, and even if it were possible I doubt it would be desirable: I usually want to just interact with people as who I am, not fill in loads of backstory and self-dissection every time I talk to someone.

And please read that ping-pong post if you have any inclination at all to assume things of this nature, it will save me and possibly you a lot of trouble. I’ve also written a longer disclaimer on assumptions to disabuse people of many further assumptions.
