The discussion here is about kids that are NORMAL, not weaker. And for a wide variety of excuses, our yeshivos (that are constantly pressuring us to support them, even in hard times) are saying no. What these yeshivos are essentially doing is giving the ultimate rejection. We are not referring to any yeshiva who lacks the extra services refusing to accept a talmid that needs these. We are loking at the stark refusal to do the job they tell the world they fulfill by all their fundraising events. What blatant contradiction.
Often, the word is that there is no space. This is a lie more often than the truth. If the rejection occurred after classes were filled, it might be a valid excuse (maybe not a reason, but an excuse). But we are looking at early applicants that are turned down for arbitrary reasons. If only the philanthropists who support these mosdos would examine the admission practices and rebel against those who are so CRUEL, we might see some of these corrupt, egotistical, selfish, and sadistic attitudes change.
