I don't play the 2-4, but if it as an uber loose passive bunch, I like a raise. Yes, someone might have limped with KQ or AK, but I think its MUCH more likely (assuming uber loose passive) that (1) your opponents have complete garbage (i.e. you have a pot equity edge, however slight), and (2) 1 or more of them will pay you off all the way to the river if you hit TP good kicker and they have any piece or pkt pair. Add to this that even when you miss the flop a good % of the time you can expect to see a free river card with 1 sb on the flop and its an easy raise imo.

You should definately raise on the button if folded to you. This is more likely a value raise than a steal in that situation.
