Well then you're turning it into a bluff, and I don't think this is the right hand to bluff here in this spot. I don't think people are folding Ts or better Js to your pat-bet. The line looks fishy, so they'll look you up with their bluff-catcher (Ts and decent Js make good bluff-catchers precisely because people make a bet here with worse every now and then).
If you want to bluff, do it with a similarly bad (or worse) draw where you've paired 3 times or something, so you know most/all the 3s or 4s etc are dead. As you might notice, that means you're not bluffing here very often, which is also probably a good idea.
More importantly, if they've checked behind after you check, just draw. The pot isn't monstrously large - aim to get a value-bet in on the river.
As far as the induced bluff-raise...that's a good point. He could indeed attempt a bluff-raise. However, if you've been playing with this player for any decent amount of time you should have a decent read in order to re-bluff or call off with the Jack. (This would be difficult indeed, but not impossible)
Re-bluffing with a hand that is ahead of basically every hand in a 2-7 players bluff-raising range doesn't make sense. If you think they are bluffing and will fold to a 3-bet, you should always just call. The only reason to 3-bet would be for value, if you think they'll only ever raise here with a range that is comprised of <50% value hands and >50% bluff hands that they'll call your 3-bet with. I don't think I've ever had the confidence in my read to try that play.
You'd have to play with someone for quite a while to know that they'd never make a seemingly random bluff-raise. They might only do it in this spot when they catch another 2 and they've seen all the 2s, or they might do it when they catch a straight, or top pair, or something else that you could play a few hundred hands with them and not see. You'll just pay off too many value bets if you're calling raises with this hand and presumably all better ones.
If you x/c the river, you still allow them to make those same bluffs, but it only costs you one bet. At these stakes, the hands they would try a bluff-raise with they would have bluffed when checked to anyway.
