In class I have to write an argumentative essay. I was going to make it on the topic of abortion since people have such strong views about it I thought that would be a good one. Well my teacher used it as an example and then said we couldn't use that one😂 does anyone have any idea? Maybe gender roles or gay marriage. I don't really know because I'm not a strongly opinionated person I just think people should do what is right for them and no one else. I really don't have an argument for anything does someone have any ideas?
