Definitely it should not be patronizing. Presentation was so bad for various important topics (burning fossil fuels, nutrition habits, sex stuff, etc.). Still, personally I try to let myself challenged even if the argument is patronizing. I don't want to say "I will not do X because you made a patronizing argument!". But for the cases I conclude it is actually a good idea, I will try to explain to the people making the argument "you would have convinced me easier if communicated like this".
