Sorry to hear about your problem, but as others have explained, the growing intolerance and belligerence of the political left only assures that it will get worse. Just today a friend was telling me that he had just returned from his latest trip to Gettysburg. Unfortunately, it wasn't as enjoyable as his previous trips. Everything was going great until he and his family got to some of the larger Confederate monuments where there was a small group of a certain ethic background screaming, hollering, waving banners and beating on the monuments with signs on sticks. He confronted the woman leading the group and she and her group then went after him. He escaped with only a few scratches on his car.
It could have been worse. Back in about 1996, I was working in a local gun shop when I received a phone call from one of my customers. He was an older, retired fellow who was normally pretty calm, cool and collected. In this case, I could tell by his voice and he was tired, frustrated and angry all at the same time. He explained that he was calling from Niagara Falls, Canada. He knew that I had a friend who had a trailer for hauling a car and was wondering if I and my friend could drive up to get him and his car. I said, sure I could, but what happened? Did he have a break-down? Fire? I needed to know what happened so I could decide what tools to bring. He said, no, it wasn't a break-down or anything like that. He and his family had decided to go across the boarder to see the falls from the Canadian side and when they were coming back, the Canadian Boarder Patrol (or whatever they are) stopped him and asked if he had any "contraband" or "illegal items" in the car. He told them "no, nothing illegal," but just about that time they noticed the NRA sticker on his car. They told him to pull over to a spot near the station for inspection and after he did, demanded he and his family get out and "come in the station to answer a few questions." He did and four hours later, when he was allowed to leave that little station and the interrogation they put him and his family through, he discovered that they had taken his car apart! Not only were the tires off the car, they were off the rims, the seats were out along with most of the interior, the gas tank was out, and large parts of the engine were scattered around on the ground. No apologies, nothing other than something like "we know all you NRA types violate our laws by bringing guns into our country, we just couldn't find it... this time!" My buddy and I scrapped the NRA sticker off of his car and drove to Canada to bring him, his family and his car back to freedom!
PS. There are a couple of products out there that will take care of that stick residue on your vehicle. Try "GooGone" or "Goof Off" and then rinse thoroughly. A couple of minutes at most should take care of it.
