You get shaking heads because the live donks are thinking "damn why does he keep going allin ? why can't we just see a flop and play REAL poker ?"
It depends on what you think is going to happen if you minraise , consider player stacks and tendencies behind you .
If you're likely to get shoved on but not called then you want to r/c your strong hands and r/f some weak Ax Kx Qx etc with blockers - r/c QQ shove 98s and r/f K9o for example
If your minraise is more likely to get called than shoved on , then you want to minraise your strong hands and also hands that play well postflop . Now you would raise QQ shove K9o r/f 98s
