How bad is this flop raise?

[Goat_boy]

Flop: my donkishness estimates 3 outs; getting 11.5-1 with players behind, is this not a clear fold.

PF: maybe i shouldn't just quote better poker players than me, but AJs is, according to the boy Miller, a cold-calling hand preflop. With no reads, i'd cold-call.
Tring to reason instead: unknown player could be raising on many hands but he still probably holds something decent.
AJs plays well in most situations but not HU vs. a few. BLAH BLAH.....ED Miller can work this out better than me.
