Are you sure you are making a sincere attempt because you don't seem to like dissents--you are deleting my posts on your wall.However, it is perfectly alright since it is your inherent right =)
Insults in general should be avoided.Difference of opinion is not insult but personal attacks do qualify as insults.Generally those who have no argument resolve to these tactics. I never need one to buttress my argument.
I am open to all discussions here.
