I sure hope someone took the time to be nice to him and see why he wanted to shoot. And maybe if he would support the right to keep and bear arms. Yeah it's a long shot but there is nothing to lose. I've never seen a pro-gun person turn anti but I've seen several anti's turn pro-gun.
If all he got was a big F--- You from the club, then he would have left being justified in his feelings that gun owners are rude, crazy, wack jobs that shouldn't own guns.
Remember, that no matter how much you might dislike certain people, politicians...reporters, if they come to you for help or information, you have to be nice to them or you will turn them off. Recently in Michigan there was a middle of the road/pro-gun leaning reporter. He went to a gun show and was snubbed by all the dealers and had security tailing him. Guess what, since the pro-gunners were rude and gave him nothing to write about. He wrote an article about how gun people are rude and refuse to talk to reporters. That really sucked seeing how we could have had a nice pro-gun article written.
