I'm sorry I offended you by being polite. I'm not going to let you drag me any further down this road. However, if you would like a very short course on how mRNA vaccines work, and why they're safe, I will be glad to offer you this.

You are free to refuse this offer. I have no power to coerce you either way, nor am I going to help you further turn this comments section into a shit show. However, if you accept, my expectation is that you do so in good faith.
