How can someone be too yeshivish? Wherever you are in life, good for you.
You are correct.
Either way, what exactly does “Yeshivish” mean? And does too much of it mean they attended too many yeshivos?
Whenever criticism is offered in an abstract way, where a behavior is not criticized on its own, rather the whole person is being criticized, I dismiss it. Each person must be seen on their own (in a case where it is our job to judge. When it isn’t..). People use code words when their critique lacks proper merit.
