I apologise if I am too direct, but cannot help it, but say, that these are extremist ideas. Why should relatives or friends be held responsible for actions that are not theirs. In my former communist nation, if one person went against party line their entire family would be prosecuted. The statements you made are unfortunately not hard to find being drawn in the minds of many, however, they are a bitter memory for those who have lived in times when this kind of thought prevailed. The past should serve as a teacher. Unless there is actual proof of their wrong-doing they are innocent until proven guilty, and as such merit the same treatment as anyone else.
