Of course there is a lot that we can do! Step one is to not post ridicoulos discussion such as these for all the world to see. If you have ever spoken to non-frum Jews (i suspect many commenters here have not) you will hear a major fallacy circulated that frum Jews do not consider them Jewish. If you actually believe this (like that Moron MK Azoulai) you know nothing about Yidishkeit. For all those in this coffee room that say “kol yisrael arievim…” only applies to frum Jews, would you also say
You can not be yotzei a non-frum Jew in kidush?
If a non frum Jew is drowning would you save him?
There is no such concept as Teshuva?
The list goes on
It is true that many who consider themselves as Jews may not be halachicly Jewish. But many if not most are.
A Jew is a Jew is a Jew
Hitler Y’M knew that. It is about time we do too.
