Resistance comes in many forms, some big and some small.
I don’t know if you heard, but last night a mosque was burned down in Victoria, TX. The cause isn’t known, but it was striking that this happened just hours after Trump signed an executive order banning immigrants – including refugees fleeing wars – from several predominantly Muslim countries. So if you’re up for a small act of resistance today then you might throw some money to the effort to rebuild the mosque (https://www.gofundme.com/victoria-islamic-center-rebuilding). We cannot let hate rule the day.
Other small acts of resistance that can be very meaningful over the long term include setting up a recurring donation of whatever you can afford to the ACLU (https://www.aclu.org/), the Council on American-Islamic Relations (https://www.cair.com/), or the International Rescue Committee (https://www.rescue.org/).
