Is it wrong

Why would it be wrong?

It's good to be strong as long as you don't abuse your strength.

Depends on what that means.
It's not wrong to just be a strong person. But I think it's wrong to pretend to be strong and bury your emotions, cause that'll mess you up. It's also wrong to abuse strength to take advantage of the weak.
It's like that spiderman thing: With great power comes great responsibility :P

No. Because only the strong and smart would survive if we stopped getting in the way of Darwinism. But some smart and strong people decided the dumb, weak ones were worth saving. Now they plague us with their awful grammar, win lawsuit cases for somehow hurting themselves, and try to impose their illogical moral codes that don't really help anyone or anything but their conscience for some reason.

We need 'strong' people and we need some less strong ones. And they all need to play nicely.
