I rarely post my comments but i feel here i have to.
I am repulsed by what i read as making fun of the intention of The Shabbos Project. If you aren’t interested in having those who are less fortunate than you or less frum than you at your table, than by all means live in your own world. Don’t invite anyone.
There are many that don’t need a “Shabbos Project” to be inspired to invite strangers into their house for a shabbos meal and perhaps build a relationship that will plant seeds that will last several lifetimes.
The idea to promote kiruv worldwide is admirable. It gives many people the chance to get involved in something that, IMHO will hasten the coming of Moshiach. If you not interested stay out of the way of those that are.
