Touching a women boob without her consent? Harassment

Hugging a woman without touching a boob, but without her consent? Still harassment, but not at the same level.

Hugging a partner without their explicit consent, but it’s month that there is an appreciated flirting? Likely not harassment, maybe uncomfortable, but context is important for a proper judgment.

This is true for man and women.

The rest is you hating another social group having a strong opinion in the matter

I agree, there both harassment but not the same level. 

It's harassment if it's touching without consent. It's sexual harassment - which I feel is worse - if it's touching an area culture treats as sexual. That's why it's not the same. 

There's really no male equivalent to breasts, but for demonstrative purposes, I think most men would consider a dick grab *much* more violating than a chest grab.
