Someone who is left wing is going to be more socially involved with society. As they are someone who likes society and sees it as good they will be more interested in being a past of it. Thus they are more likely to have social relationships like having a gf. Also if someone is given social relationships, they will be satisfied and think society gives them what they need to be happy.

But someone who does not like society and does not see it as good will be less likely to be a part of society and thus less likely to have social relationships like a gf. Also if someone is not able to get basic relationships out of society, they will not think this society is that good and will fell alienated from and also will be more likely to criticize it.
