You are using that "serious caveat" because it's the go to trope for anti-maskers seeking to pollute absolutely every fucking discussion on this subject.
I asked you to explain why you're posting anti-masker arguments if you are, as you claim, "all for masks" and all you've done is repeat the same anti-mask bullshit.
Next time I won't bother assuming possible good faith on the part of anyone spouting textbook anti-masker noise.
The ECDC guidelines recommend face coverings but still recognise the caveats, but in your eyes they are heretics and anti-maskers for even mentioning it. You appear like a religious fanatic. Very sad to see and it completely kills any serious discussion about the topic.
When you were informed that Scandinavian countries are not taking an anti-mask stance, instead of holding your hands up that your argument was based on something false, you simply carried on making the same anti-mask point by fixating on something else (three sentences from a six page PDF) instead.
Like I said, you are not fooling anyone.
