Is there a way to even the odds agaisnt them?

You'd better believe it! Avoid their channel and suggest that your friends do the same. When the hosts of that channel have no chatters left they'll then understand why.

There's no law against complaining but it's usually fruitless. Opers don't usually meddle in channel politics and if you repeatedly request they do it might earn you a clout across the ear (/kill).

Just avoid these chat nazis, if your server allows it make your own channel, take your friends there and make your own easier to live with rules and life will be easier :-)
