Should we recognize more than two genders?

This whole gender debate and what bathroom to use is kinda silly. It doesn't take much to design a single sex bathroom that accommodates everyone. Been in a few, each stall was separate, with door the close off each stall, you walked in picked any stall did your business walked out to the sink area, and washed up. Yes there were urinals, in a small stand up stalls and clearly marked are urinals. Easy yea the first time I was in there it was a little bit of a shock to see women in there too, but nobody ever saw anything and once you used it once or twice you did't think anything about it.
