These kind of groups are not worth joining man. They are often honey pots that feds most certainly know about and track and infiltrate. They attract people who are not mentally or metabolically well anyways.
Its perfectly fine to care about the well being of white people as an ethnic group in Canada if that's your thing, but your intuition is right. Focus on getting the best education and networking you can in college. Form communities with healthy, positive, happy people. Disgruntled unhealthy people as a social network is a downward spiral.
