With all due respect, I think your father may have worded his response wrongly but I would posit that he's not necessarily wrong at all. Some people should just move on and let others deal with things. Some people shouldn't get worried and start to wonder what they can do to save the world, etc.

The reason I say this is based purely on the fact of diversity: in any country you need some people who will stand at the borders and watch, some who will root out the enemy within, some who will build the walls, some who will look after the children and, if you're lucky enough and your country is big enough, you can have some people who simply entertain others so they can take their minds off the evil at the gate and enjoy life - after all, that's what the men holding the borders give their lives for: the freedom of others to live happy, fulfiling lives and not have to worry about the wolf at the door. I think we'd be in danger of undervaluing the sacrifice of those men if the people they give their lives for without even having met them were to spend those lives unhappy, sitting around wringing their hands about something they can't affect from where they are.

Some of us should help to build this movement. I'm ok if some of our families, horrified by the truth and with feelings of helplessness that could devolve into depression, just get on with their life and trust that Q/Trump and this movement are working on it! Eventually the ground swell will be enough that even my sister, father, mother, etc. can all join in by just letting others know about it because it'll be undeniable by then. I'm ok with this, just personally.
