I 100% disagree with your opinion. The first email I received was an impersonal acceptance email, the second was asking if I had any questions and that I can view my acceptance letter on their portal. To receive a "you didn't respond to our last email so we're gonna revoke your acceptance", ESPECIALLY during a time like this is absolutely undeserving and represents the school poorly in my opinion. I could have been severely impacted by the virus, a loved one could have passed away (both of which happened) or I could have lost power due to the natural disasters that have inflicted several states.
This has nothing to do about being entitled. Instead of making personal attacks against my character, recognize my point of view. Just because I could not find the time within a two-week span to send a thank you email, they assume I'm not interested? You guys are absurd if you think that is normal or by any means warranted.
If you want to let it go, then do just that. Agree to disagree. Don't build upon the argument.
