Crowds are very subjective. What is crowded to one person is not crowded to another. It's very difficult to gear how you would feel in a situation based on someone else's interpretation.
For myself if I was going right now I'd ask myself if I was ready to be around a lot of people, in close quarters and not able to avoid the situation. Knowing how I would feel in that situation would help me decide if now is the right time for me to go or not. Reality is that at Disney there most definitely will be times when crowds cannot be avoided. I ask myself, 'am I okay with that?' and go from there.
We live in an area where social distancing as still a part of everyday life. 2 weeks ago we went to a birthday party for my nephew at a trampoline place. I needed to consciously remind myself to take deep breaths as I was overwhelmed by the number of people there. In reality and compared to many places, there really weren't a lot of people there, I am just not used to being around very many people. What seemed crowded to me would be laughable to many.
