Calling a raise in the BB with Ax suited

[SinCityGuy]

This applies to legitimate raises, not to steal raises. I've read conflicting recommendations on this. I happen to think that it's a -EV play, unless there is at least another cold caller before you in which case you have the implied odds if you flop a 4-flush. If an ace flops, you have a good chance of being outkicked.

What are your opinions on the subject?
