Typical jerk response, republican jerk I would add. Can't win an argument so he goes on personal attacks. On top of that he throws some distractions hoping he hides his ignorance in the noise. You just lost any moral ground that you thought you had.
First, I'm still waiting on your great "converse, inverse and contrapositive" interpretations, so far has been crickets about it despite wasting an entire page of replies on it. Oh, you were engaged in pointless banter.
Second, my credentials are fortunately not for you to judge, I might not be an expert in much but on my job I'm quite good and I have no problem discussing in more details. Thing is you are not that person to question my credentials..
Third, and this is the distraction, you throw this study as if there is any opposition between that article and what I'm saying. Newsflash, you don't know what you are talking about. This SARS-CoV-2 is a RNA virus. All RNA viruses mutate, some more than others. It's not secret this one did too, the question is what it mutates, how often and if there are key portions that are stable and can be targeted with vaccines. But you don't actually care about this, only to say it's just as flu. Spanish flu was just a flu, right?
First, what makes you think I was talking about you? There are a lot of arm chair experts here, with me being the biggest.

You take things too seriously.
All I was doing was provide more information on the fact that there are 30 strains now. That can make it kind of difficult to handle, or maybe it does not.
