He can have a ton of stuff here, QJ comes to mind which we beat, random jxss etc... there are also a lot of hands in his range that have us dead but he shoved for half pot so this is a snap call and reload if you lose, not really thread worthy OP (not trying to be condescending when I say that, just letting you know that this is a super standard call and if you lost the hand you shouldn't need to second guess yourself etc)
oh yeah and try to not go under the max buyin, you're costing yourself a ton of ev
and about his comment, it doesn't change anything for me...if anything it makes me want to call more, don't let people's talk manipulate you... this is a call, and that's all there is to it
