I used to be extremely critical and would shoot down every idea (instead of offering positive feedback alongside the negatives). Most importantly, I wasn't paying attention to how people felt about my style and was focused on improving their overall ideas. I often disregarded the human motivating factors, which I found to be detrimental when cooperating with other individuals.
Live and let learn. There will be a time when the NT may consider the emotional impact of their words. For now, I'd say give them a run for their money. Get your debate gear on and prove how narrow-minded they can be. Ask clever questions. Avoid being baited; the more you allow them to push you around, the more they will do so. Stay cool, ignore their pompous attitudes, study their weaknesses and beat them in their own game. Your Ne can offer a major leverage when generating new ideas. Use it to your advantage.
