I have never thought someone who is rude is jealous; I just figure they don't have a good answer to give so they resort to childish behaviour.
As for criticism, that depends on how it is presented. If they say that they disagree with me and why. I am good with that. If they say they disagree because they think my point of view is stupid, but not tell me what their point of view is, I think they are lame-brained and ignore them.
Ridiculous statements are made by ridiculous people. Like James, I am just glad to be me, and not that ridiculous person.
Mostly the people that criticize and argue with my opinions,are just Bitter,and have Miserable lives.They are just looking for "SOMETHING,ANYTHING" to disagree with, Usually I'm just glad I'm not Them. :)
I don't think any such things; I just find out everything I can about them and keep their addresses and phone numbers saved in a "persons of interest" folder on my computer.
