Your argument may be better received with less hostility. People are going to criticise your ideas throughout life, however this reaction could be seen as a distraction to your focus on the subject. Everyone is at dismay at a topic, and many topics have the capability to become heated, yet you will be amongst greater levels of respectability for future interactions if you consider refraining from attacks today (even if you feel as though this is being done to you).
Just trying to help, not scold. There's always a better way to get your point across without making people dislike your comments, is what I'm essentially trying to get at.
