People pay a bunch of money to make their cars look absolutely ridiculous and broken, hurt performance in the process, then post the pics online and get upset when people point and laugh at what they've done...
Yes, you do have the right to do what you want with your car, and everyone else has a right to their opinion of it. Comparing it to a fat wife is retarded.. unless you spent several thousand dollars to make your hot wife fat and ugly, then posted before and after pics on forums expecting praise. Then it's a valid comparison.
