Why do people jump to conflict so easily?

I do a lot of reading out there and always get baffled by how quickly people see "evil" everywhere. The most recurrent case is when people immediately call "Machismo" or "Misogyny" as soon as there is a picture of a woman with no much clothing.

I understand women don't appreciate being "objectified" but my question to them is why is this a sign of machismo:

But this isn't a sign of feminism?

Isn't it the same thing?! Football-related picture with beautiful people in underwear. Why is it that if we show women in underwear it's evil, but showing a guy isn't. NONE OF IT IS EVIL!

People just like looking at beautiful things like scenery, paintings, pictures, and hard bodies REGARDLESS OF GENDER!

So come on, let's all take a nice deep breath and relax a little, no need to shout wolf when there's a picture of a beautiful person around.
