Hate to tell you this but there are over 200 municipalities in the US with bylaws on the books allowing people to use the washroom corresponding to their gender.  Add several states, any number of school districts, and who knows how many private businesses to the mix and, if there was going to be a problem, you'd have seen it by now.  Instead there hasn't been a single case of a transgendered individual causing a problem in a washroom.  Not one.  Fact is, the people at risk of assault (physical and/or sexual) are the transgendered individuals themselves, not the general public.

After all, if this was your daughter would you be comfortable sending her into a men's room?
