What's wrong with playboy magazine or strip clubs ?

Absolutely nothing, men like to look at beautiful things and people. I like to look at beautiful things and people and I'm a woman. 

i dont think theres anything wrong with it

It is not ideal for a stable life. A lot of men are wanting to have sex with those ladies, and being in an environment for a living where so many men are trying to get the lady drunk or cohereced does not make for a great lifestyle and a lot of those ladies do end up doing things they never originally intended, or end up in hardcore movies et cetera

There are nothing wrong with them as both are the things that make the men happy. As long the women are not being disturbed, then it is fine.

they represent women as objects.

often only to serve men

If you don't see how that's a problem, you're a sexist pig

There is nothing wrong with such magazines or strip clubs. They are not for everyone, but if some like them, then fine. I have been to a couple dozen strip clubs and people seem to be having a nice friendly time.
