Canadian visiting Yosemite/Sequoia end of May: is it still a good idea?

My boyfriend, my baby and I are suppose to visit Yosemite and Sequoia in the end of May, we are wondering if it is still a good idea because of the cuts in the NPS and because of the social climate in the US (we are from Montreal and looking to the US from the outside right now is kinda scary for us).

I have some concerns: Will it be too crowded to be fun? If I do not go do I help as I am boycotting, or else does it makes things worse since we need to prove that we still love the parks under the NPS service? As a Canadian, should I boycott the US all together since the trump administration is trying to make an economic war on us?

I am kinda lost honestly, is there other Canadians here in the same situation?

EDIT: I had already made reservation for campsites, campervan and plane. If I decide to not go, I'll need to cancel everything!

UPDATE: I have cancelled the trip! I'll be going somewhere in Canada or Europe! I hope that everything will be ok in the end and that the National parks won't be too damaged from all of this.
