I am being Moche lmaan kavod hatorah!! You are being motzi Shem ra so blatantly!
While there are some yungerlite in kollel who are not doing the right thing and waste time etc.. There is certainly not a majority, not even close!! By far the majority are ehrilch yungerlite sitting and learning shark. To say that the majority are “fooling around” “not take learning seriously” “don’t belong in kollel” is outright sheker, motzi Shem ra, mevazeh talmidei chachomim and you may have no chelek in olam habah! Please think what you say/type before you hit the post button.
