Are you seriously suggesting that refugees engage in these activities? Or are you redefining "refugees" to include other people that are somehow in the same ethnic or demographic class?
For example, after WWII, German people were probably the largest demographic class of refugees [1], yet German people were probably also the cause of the greatest amount of deaths by torturing, killing, and enslaving (although they might come second to the Russians by some measurements; being only second worst does not invalidate my current point). If you argue that it wasn't the refugees themselves doing the bad things, then you must also take that argument to the modern-day refugees that you use to compare to those WWII refugees.
Absolutely serious that elements of the refugee population belong to groups that engage in torture/beheading/rape/enslavement. We have no idea how to tell the good from the bad. Just takes a small number of radicals to cause huge damage and disruption. Not worth the risk.
elements of the refugee population belong to groups...
This is categorically different to your grandparent statement implying by negation that "refugees[...]have elements that were beheading, torturing, killing and enslaving".
Group T (terrorists) might intersect with group R (refugees) (suggested by "elements of [R] belong to groups [T]), but there is no evidence of this and even if there were it would likely point to a quantity that is well below the margin of error in sampling. This is an entirely different logical statement to "elements of [R] do the evil things of group [T]".
You must be clear when you make scaremongering statements that suggest refugees engage in terrorist activities, because your first statement was clearly wrong yet emotive and therefore easily spread. This doubles down with your second statement, particularly when you have zero evidence to support your restated claim.
