Anyone who grows up thinking that two - or more - consenting adults can’t live or love together is a(nother) victim of that (in the legal sense only) “crime”.

Ah, but then they're a victim of the illegitimate criminalisation of LGBT relationships, not the victims of the LGBT relationship itself. Meaning the crime has no victims, the law has victims.

Where I currently live there is an old and much copied legal system but I’m not really qualified to think about nor answer your second question.

Sure you are, don't put yourself down like that. All citizens living under a law should have their say in the justness of that law.
