The law regarding sex and pornography.

I don't know how it is in other countries, but in Poland the law says that people under 18 can't watch pornographic films, yet people who are 15 and over can have sex. 

That doesn't make any sense to me. When a person is mature enough to have sex, why aren't they allowed to also watch it?

Maybe it's because of the kind of sex shown - brutal and disrespectful towards women.

"Without respect to ___" has an academic use, meaning "not taking ___ into consideration" or even "not including ___".

Anyway, in my view there should be the same age should apply to those two laws.

Many of the corrections are actually suggestions for a more natural style. The "note-style" (ie. using punctuation and spacing to structure your information) looks a little ugly in English. It's better to show that you can write a regular sentence.

Good writing anyway - yes, it's strange that laws like those should be so inconguent. I recall in my city, there used to be a law against being drunk in public... ignoring the fact that a bar is a public place! Those rules have since been revised to make sense. :)
