AJ facing pre-flop raise

[Messy Harry]

READS: UTG+1 was kinda loose and could call down with inferior hands. MP2 was kinda tight pre-flop, but kinda weak post-flop and would tend to fold hands on the flop if he caught no part of it.

Reads notwithstanding, I still feel like I'm wasting money on plays like this, not to mention opening myself up to bluffs on the end (like here?).

Fold pre-flop since it's not suited and there's 4 yet to act?
