Welcome to the community.
There's nothing wrong with wanting to make strong characters. Most people misunderstand the meaning of the term Min/Max because a lot of players who want to cause grief Min/Max their characters as a method of being a jerkass. If you want to make ridiculously powerful characters just to mess with people and be a dick, you probably won't like this community. That's called 'Being a Munchkin' and it is an entirely different thing from Min/Maxing. You can read The Gentleman's Agreement in my signature for a better idea how to handle Min/Maxing in a party.
Pen and Paper Roleplaying Games are a collaborative effort where everyone comes together to have fun and put in effort together to tell a story. If someone joins just to cause trouble they're probably going to be kicked out fairly quickly and gain a reputation as someone not to play with.
