It is better if it is a clear separation of the male and female roles that gays can not and do not provide.  Men and women have a number of differences that children need to see and appreciate.
Yes, men have done some damage to their reputations but most of the criticism is undeserved.   For instance why are men almost always the ones accused of domestic abuse when women can be just as guilty?   Why are there no safe houses for men with wives who are abusive, some physically so?  Why are men always assumed to be the rapist when women are just as likely to take advantage of men?  Women are also more likely to sexual extortionists.  In the workplace, it is assumed the man is the one sexually harassing the woman, when the opposite is just as likely.   There is a reason some women are thought to have 'slept' their way to the top.
