Responding to sideline / bleacher chatter

[stegenref]

I'm in my second year at the high school level and working the HL position. One thing I have trouble with is when I see a foul (e.g. a block in the back or facemask), sometimes I'll hesitate for a second or two before I throw my flag...like I've heard that you should do. But where I run into problems is when I'm going through that split-second decision time of whether I saw a foul for sure and if I should throw my flag, someone from the sideline or the stands will yell, "That's a block in the back!!" or "Facemask!". It pisses me off and makes me not want to throw my flag...especially since I don't want it to appear as if I'm throwing my flag in response to their shouts...I'm afraid that will just invite more of the same.

I know I should just call what I see, but what are your thoughts on how you mentally deal with that issue?
