Your right, people have their own opinions and that is what makes us all individual. If someone voicing their opinion bothers you than you should be gone. If someone says that the R/C car I drive is a piece of crap thats cool because as long as Im happy with it thats all that matters and what they say doesnt bother me. When people start making comments about you personally then that is when it becomes a problem and shouldnt be tolerated. Deal with the opininons, not the attitudes.
