It is a minhag Yisroel to criticize others especially when it makes you feel superior.
As a Rebbe of mine once says “ITs hard to be frum its much easier to be frummer”
So instead of working on ourselves we say
“Hey at least I’m better than all those going to ORlando who are don’t have the “therapeutic exercise” (whut?) of cleaning”
or
“Hey at least I didn’t go to a Pesach program in Dubai that serves deer meat”
Or
“Hey at least I’m better than the bitter yidden insisting they aren’t jealous of those in Orlando and that their way is better”
ITs an old minhag
one I’m being mekayem right now
