Why men cant ware a bra?

hi there, i have been reading a lot of questions and the answers about men wearing a bra. a lot of replys where men should not because there for women and if your gay, i never realized how ignorant and immature our society is. bra is not for women, it is for breasts support weather or not it is a medical condition, fat, implants what ever the case may be. it is breast support. the word brassiere comes down from an old french term as chest protector that refers to the armor in old military times. so the first to wear bras where actually men. and there are plenty of men that have moobs that are not gay and looking for some support or comfort, and just because there not gay they have to not have put up with it when women dont because of what our society has made of it, talk about double standards no one like double standards. men do have brest men can even get breast cancer. men that think they have pecks yes but have breast tissue ther to. one of the answers i found was men should ware bras as often as a women should wear a jock strap, my thought was men have breast, women dont have balls. but to each there own. why is it that our society made bras only for women? and men who would like to weare them have to be scared to, and made fun of?
