Elvi the comparisons you use are completely of a different spectrum here.  We are talking about biological males or women being in a restroom with a young child of the different sex.  It isn’t just that bad people could potentially use the law to their benefit claiming they are transgender but it is about the potential exposure that could even accidentally occur in a situation like this.  I for one have nothing against transgender people but I don’t want my 8 year old granddaughter to walk in and see some woman with male genitalia exposed even if that risk is minimal.  In that logic, what is the difference then of them using the biological assigned bathroom?  Why can’t a woman with male genitalia use a men’s room? If a young female has to be potentially exposed to that, what’s the difference of them being potentially exposed to a male with male genitalia?
