Thats extremely judgemental, maybe some people feel rejected by the yehsivish community but still value judaism and want to stay religious. Did you know chassidish people that become yeshivish are considered off the derech by many in their community. Everyone thinks staying in their community is the best but everyone needs to find what works for them, as a religious jews serving hashem, and do it
Dont be so quick to judge thats a very insensitive statement!
