I have changed somewhat. For my political positions, I have become more liberal on the economical issues, but I have become more confident in my positions. I don't think DP had a large effect on me, but my experience from looking at countries/states such as Taiwan and Hong Kong turned me off libertarianism. And my travels in Singapore and China have made me more supportive of China and Singapore's model of governance, although I don't prefer it.
On immigration, crime, education, EU, Eurozone I have kept my positions, which is a strong dislike of the cultural left.
My real change is my view on the Republican Party and the American economy. I actually wanted to move to America previously, but now I have no interest in doing that. I really despise the GOP establishment, and believe they are corrupt and don't care about conservative ideals. There is the Tea Party, but they are too dumb and extreme, hence they promote dumb policies, and often have to have people making their policies if they are going to make any sense. Also, they are too dumb to come together and fight off the corrupt establishment or even know who is a Tea Partier or an imposter. It is obvious for me that the GOP is dead, and I do not believe Democrats with their class warfare will do any better.
