If ufc, mma is legal why isn't prostitution, murder, abortion, child...

[ß®@ñÐØÑ]

...molestation, gay marriage etc in the US? I am serious.
I find ufc and mma horrendous.

Prostitution- To many murders.
Murder- Seriously what do you think
Abortion- Debatable
Child Molestation- Seriously what do you think
Gay Marriage- Seriously what do you think
Seriously all these are completely irrelevant to ufc/mma being legal as all the above are horrendous.
