I OC occassionally, and it has absolutely nothing to do with showing everyone how big my "machine" is. Nor do I choose to OC to make a political statement or to antagonize the anti-gun crowd. I OC purely for the sake of comfort. Since it is legal to OC here in Indiana, I don't feel the need to sacrifice comfort or buy my pants and other clothing in a larger size to dress around the gun. I let my clothing choice dictate how I carry, not the other way around. If it is jacket/hoodie weather, it gets covered up. If it is warmer outside, it doesn't. Regardless, my M&P is on my hip in an OWB holster because that is what is comfortable for me.
As far as OCing making others mad goes, does it really matter? Like I said before, I don't do it to antagonize anyone, but I don't really care if my choice upsets or offends anyone. If a member of the public wants to voice their opposition to me carrying a handgun, I totally respect their right to do so, but we have just as much of a right to OC as the naysayers have to complain about it. Anyway, since you seem to be stuck on the act of OCing angering others, maybe we should all refrain from voicing our opinions also, as our opinions might upset some people too. Heck, let's just go ahead and stop practicing all of our other constitutional rights while we're at it for the sake of keeping everyone else content, and see how far that gets us.
Now, on to your prior assertion that OCing a firearm WILL get you hassled, stopped, detained, etc. ... I have not been carrying for very long, but I have found, through my own experience and through reading the accounts of others, that most people are either so wrapped up in their daily lives that they don't even notice or they just don't care. The latter applies to most LEOs as well. Don't get me wrong, I'm sure there are some uneducated police officers out there that hassle people for OCing out of ignorance of the law, but it doesn't happen all of the time. In short, OCing CAN get you hassled but it doesn't mean that it WILL. Since you seem to be a huge proponent of CC and against OC, I hope you are very meticulous regarding the concealment of your firearm. If you "print" while CCing and someone notices, that COULD get you hassled.
