Translation: I probably got treated unfairly by my neighbor, so I'm gonna rob someone else because I guess he/she is rich.
Do you even know how difficult it is for 95% of the actors to get a role, regardless of gender or sexuality or whatever?
Also do you know that your logic is the perfect for those ppl to block LGBTs for straight roles? "Nobody is being 'robbed' of a chance to play a role that's specifically meant for someone else." THIS is why never use specialty to fight for equality. If your goal really is equality.
