I'm assuming that by "raising your voice" you mean to put one's 2 cents in, not actually shouting. That being said, I agree, all pionts of view are valid (at least to the one who holds them), and worthy of being expressed. It's only by hearing all thoughts and opinions that we can make our own mind up as to which opinion is best for us.
It sounds as you have been hurt or slighted my expessing yourself here on this forum. I'm sorry for that. Please don't take it personally, we all get picked on every now and then. No harm is meant.
I look forward to your voice being raised.
