Even though I knew of private gun ownership when I first came to the United States, there was still an emotional disconnect between seeing others own guns and realizing that my parents could. For people from even less RKBA friendly countries than the USSR, such as China, Koreas and Japan, that emotional disconnect may be even greater. So take your new immigrant friends shooting. Teach them the safety, and the tactics, and the political history behind the Second Amendment and the preexisting human right it affirms.
