It's true, as an acronym MBGA just slips off the tongue.
It’s harder to argue against “Make America Great Again” or “Black Lives Matter”. Their object-level meanings are fairly anodyne and positive. It’s much easier to argue against “MAGA” or “BLM”, since the meaning is obscured by the acronym.
Political movements with nice slogans should avoid turning them into acronyms.
I see no joy
I see only sorrow
I see no chance of your bright new tomorrow
So stand down Margaret
Stand down please
