Little Froggie,
Statements like “we cant let Halacha decide who to love..” or “all HaShem cares for is Ahavs Yisroel, the rest is nonsense” (ok nobody wrote that) is a slippery slope.
Nobody wrote either statement you put into quotations, so why are you addressing them at all?
I don’t think your point is wrong per se, but it is misplaced. Kind of like if somebody opened up a thread about suggestions for how to improve their marriage, and someone came in and posted that divorce is permissible according to halacha.
