Gentlemen!
By asking for gender in the registration data and the option of another gender is enshrined there, you have fallen down in my eyes. There is no other gender, fill in the blanks you know from biology. Don’t fall for fashion. I feel you are insulting all religions of this world and their believers.
Man is created as male and female and no other gender was created. I am deeply disappointed and ashamed of you responsible for this site.
You offer your “customers” promotion on Facebook or LinkenId. Know that I will truthfully communicate my findings with you on this site. Man.
