You're right that the comparison is a little insensitive/ extreme, and I respect your views on that ( not trying to go against/ or for Goro's post, just stating my own opinion).However....
Trigger Warning- mentioning the Holocaust and Hitler ideals
However, people have cited the terrifying similarities between Trump and his Hitler-esque ideals. Mike Pence supports conversion camps, and calls himself an " ally to the American Catholics" , literally passing bills that would deny thousands of women health care, and happily stating that Trump is a president for Catholics. Bringing race and religion into politics, completely defying the seperation of Church and State. Blatantly stating that he's a president for Catholics. Saying that he's violating one of our most precious laws.
Trump's demonization of Mexicans and Muslims is part similar to How Hitler demonized Jews/disabled/LGBTQ people, and how he's made Racist/people who discriminate based on religion/sexuality/ place of origin, feel empowered to spread hate and feel like their beleifs are validated/correct.
The surge of hate crimes against Muslims after trump's election rivals only that that occured after 9/11.
You're right, comparing this regime to the Holocoust is callus, to say the least. But people fail to realize how close stuff Trump says is to the very start of the Holocoust, which began with dehumanizing targeted minorities, as well as making someone else the " superior" ( in Trump's case , American white , straight, Catholics, in Hitler's case, Aryans).
Trump has started the hate and finder pointing and blaming and demonization that was at the heart of the holocoust, even if this modern presidency is nothing like the Shoah, that is totally true. I'm not doing to use that term anymore.
