“Because there are thousands of Lubavichers telling everyone to do mitzvos to bring Moshiach.”
Hashem made this world, and put us on it, and gave us Mitzvos Maasiyos, in order for us to make him a Dirah B’tachtonim. The culmination of that, is Bias HaMoshiach.
We do Mitzvos because we are commanded to do so, but this is the reason why Hashem set up the world in such a fashion.
If you want to bring Moshiach, the best way to go about it is by increasing in Torah and Mitzvos. I see nothing controversial about that in the slightest.
Gut Shabbos!
