Small pair preflop

[uwat1987]

My question/concern is kind of general but here is an example:

PokerStars 0.25/0.50 Hold'em (9 handed) Poker Stars Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

Preflop: Hero is Button with 5[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/heart.gif[/img].
UTG calls, <font color="#666666">4 folds</font>, CO calls, Hero calls, <font color="#CC3333">SB raises</font>, BB calls, UTG calls, CO calls, Hero calls.

In this case SB is 9/3/2.5 over 200+

I know that SSHE says never to fold a hand for one more bet pre-flop but I feel like I should tend towards folding in situations like this. I'd like to know what people think because this happens a lot.
