A rights group says government troops in the Democratic Republic of Congo carry out most of the rapes of civilians caught up in the war with rebel groups.
That's horrifying. Why did you bring that up?
The troops in Congo are a problem and they need to be thrown out of the country.
I don't think you'd like it if someone generalized any of your groups as rapists. Some troops in Congo are rapists, but that doesn't mean they all are.
Maybe not everyone is a rapist, but a lot of their troops there are. That is a problem and something should be done about it.
Something should be done about but when you generalize about a group people, others are less likely to listen. They might know somebody who is not like that and your whole statement will seem like a lie.
