Yes, as I have visited Sweden on several occasions I can confirm a welcoming and easy going attitude. Americans are welcome!
There is a small and most insignificant group of organized racists. The group of organized violent left is bigger.
But idiots aside, even immigrants need to learn how to behave in their new environment. There are reported instances of female genital mutilation, performed in Sweden and against the law, by some immigrant groups. There are reports of child weddings, confirmed cases with convictions in court and prison sentences, where males in a family murdered female members of the family for keeping undesired company (i.e. swedes).
Such things upset most Swedes, to put it mildly.
But all of this is off topic, not being Trumps fault.
