I think the best thing to do is ignore the rude people, let them be rude and unhappy with their life. Thats how I see it anyway. I think half of the people that are rude are very unhappy and the other half are jealous we all have such beautiful babies.
Pnut has been called, a rat, snake food, a girl.. Comments like " wow my cat is bigger than him, " is that really a dog".. You know. All the rude things in the book. Honestly I just ignore them, I wont give them the time of day.
