adjective

- annoyingly insensitive or slow to understand.

I’m not sure how I fit that description, at least in this context (though my ex-wife may disagree ). I don’t believe I’m being “annoyingly insensitive” when I asked the obvious question: “If the grandparents are vaccinated, then what’s the problem?” How are the people in this category at any significant risk if they are vaccinated?? Is there a minuscule risk that they may contract covid from another person? Of course, thats true with most viruses/vaccines. However, it is completely unethical to vaccinate one group of people in order to protect another group. That is undeniable. As far as being “slow to understand”, I think you may mean I am hesitant to agree with your point of view, which is true. But that doesn’t mean I don’t understand. Many things in life can be understood, yet not agreed with/condoned.
