After reading and re-reading this "trainwreck of a thread", I just can't get past this nagging thought that you're trolling.
May not have been your intention, but you surely got there.

I went so far as to take a peak at your history (and don't let your paranoia get the best of you yet again, I was just wondering how some one who dates back to the very early days here, has/had only 23 posts), and you went from a casual pantyhose enthusiast to someone going out.

But that time frame does represent a valid journey from the casual to the not so casual. Perhaps you were the quiet type for all those years?
Your OP started out ok I guess, but then you went all transphobic at post #23 and it got dumb and dumber from there on out.

Idk, maybe once you started getting the errors of your ways pointed out to you, you got defensive?
Something in your 'men who shouldn't be alone with your daughter' rant stands out to me: a school principal? Wow!

13 years here and you've learned nothing at all about the trans experience; you never took the time to read about the trials and tribulations of trans-folk, the pain and heartache, or conversely the joy and happiness of getting past the fear (and you got that by the 55 gallon drum) to acceptance?

Frankly you have earned every bit of the vitriol and anger you've been handed to you.

To answer you original question about which bathroom to use "or none at all?"....yes, you should prolly not use any public facility!
For you and your families safety, and for everyone else's as well, just don't.
