Actually I find it really helpful when talking to libs to talk of a hypothetical where the CPC splits into two nominally separate parties. Both vow to continue the same policies in Tibet, Xinjiang, South China Sea, etc and the only difference is that one party is pro guy marriage and abortion and the other is anti.

I ask if these two parties have elections, whether its real democracy. Almost always, they say no.

Then I ask them how the American system is any different.
