I hate university because of the international students
Is there a reason why you hate them?
They are taking my place in my classes
It's wrong to be racist towards people from different countries. They earned that chair just as much as you did and they paid for it too.
My parents are paying for it too, so I should be the priority.
Just because you're from this country you're not entitled to get special treatment. It's not ok to hate people just because they're from other countries. Make them friends and you'll realize they're as good as you are.
