Masculinity is okay, toxic masculinity is not. It is just as important to support men and end the toxic masculine stereotypes as it is to support females. Again, being masculine is okay, but *toxic* masculinity effects everyone horribly.
Also, breasts are secondary sex organs. Guys have breasts too. And it's considered totally okay for a guy to be walking around without a shirt. Guys breasts can even produce milk under more resticted circumstances than a woman's breasts can.
