It's not terrible to defend with. I just don't like playing unsuited Ace-little type hands. I would just wait for a bigger hand if I suspect he's stealing, and open up with 3town.

It's much better for metagame if you can pick up a really solid hand in the BB and really make him spew against it. After you get to showdown and he sees you are 3banging and raising with a legit hand, then you can abuse this image later by 3 banging hands like these, and narrow his stealing range and also pick up pots by 3banging and autobetting flops that miss him since he fears you have a big hand again. Also if you decide to defend with hands like 98 later on, and he plays back at you a little, get to showdown and you might win pots from him on low boards since he figures you have all overcards.
