Alkaline Trio?

I really like these guys,but after seeing some videos recently and listening more to their later stuff,I have to ask it: are these guys emo? Like i said,I really like these guys.Some of their songs rank among my favorite (Goodbye Forever,Armageddon,Private Eye) and I was just wondering.

Would it matter if they were emo?

probably

i like mercy me and fuk you aurora

I like most of their discography.

Remains is very good.
