n00b question about stealing blinds from loose players.

[TJO]

In best case scenario the players on my left are weak/tight ones. But often I can not get the best seat and I'll have loose coldcallers on the blinds or even worse a maniac on my left (usually I'll change the table if this happens).

Pokerstove shows me that against a player with two random cards I have more than 50% equity with hands like:
22+,A2+,K2+,Q2s+,Q5o+,J6s+,J8o+,T7s+,T9o+,98s+. Also 65s,76s,97s and 86s are probably good enough because of the implied odds.

Am I not raising for value with these hands more than just stealing? They all have more than 50% equity against a single opponent and I will have position. So am I right to raise these hands everytime OTB even against loose opponents who don't usually surrender their blinds if I think I can play better postflop than they do?

Does it really matter what type of players are on the blinds in a steal situation as long as I'm a better player than they are?

(It would have taken forever to calculate the equities against two opponents with two random cards).
