I don't want to win any argument. I'm not in the mood to show "You are wrong" (something I do at work, why should I do that here?), although I'm almost always open to learning something new.
If instead of being humorous, is striking a sensitive chord, well, it wasn't targeted for you. And that's OK. If you want to hear different opinions, nice! You want to keep your beliefs, even better. What to have a clash of scientific evidence? Well, we can do that another day.
Love you gals/guys.
