I won't be upset if somebody would ask me to clarify what I am saying.
Even if somebody would call me plainly "stupid", it's OK with me.
These are just ideas, they can be improved or not, but has nothing to do with personal attacks.
Well, then here´s some news for you - not everybody is like you (thank goodness!!).
People do not have to like insults just because you do not mind them, and what you said was an insult, a personal attack, not a mere asking for clarification. 

The sad truth is that you are a bully - you have singled out several people on this forum by now, and once you have, you keep harassing them, always appear where they post,  getting personal in your replies ... You either stop this now or go find yourself another board. It´s as simple as that.
