Should I stop talking/writing about my opinions and experiences?

In the last time there are more and more people who doesn't care about what I've said or to whom I've talked. Is it really so hard to understand others?

For a short while I left a German forum because the people became more and more verbal aggressive to what I've written. I never did insult anyone personally but I would have been insulted by them. I only argumented with facts but they didn't realize it and even claimed that I would have no answer. They changed my arguments and built another story out of it...

This was the point when I left this German forum with the kind words that I'm a peaceful human and I'm leaving before I'm exploding. I don't like such "side talks" because they are hurting my mind so much. All the energy for people in need of help is flowing into nothingness because of the EGOs of contra-workers. It doesn't make any sense to me...

So, is it better to keep silent - to never try to help others with their dilemma, or to talk about my own opinions and experiences? Well, I thought that forums were made for this but who really knows???

What's your opinion to this thematic?
