While you may prefer it when people pull their masks down to talk to you. I would bet there's going to be another lipreader who would be aghast if i were to pull my mask down to talk to them. I'd need to establish you were okay with it first and that the communication is important enough to justify the risks. Even then it's not unreasonable to refuse unless the communication was essential, a genuine health risk is going to trump communication 99% of the time.

While i would be okay with doing this as i'm vaccinated and in a low risk category and don't live with high risk people, if that wasn't the case (most people) I wouldn't under any circumstances pull my mask down unless the communication was life or death. I would have a choice between inflicting a horrible death on myself/others or making your life unfairly difficult. And as unfair as that is to you, choosing the second doesn't make someone an asshole when you consider the options available.

The only solution I can think of would be everyone wearing clear masks/shields, but since they aren't widely available and are more expensive, I don't think it's reasonable to expect most people to do it.

I think your anger (justified as it may be) is being misdirected here and your response doesn't really relate to the comment you're replying to.
