Your description of the parliamentary process for selecting a prime minister isn't all that accurate. The party leader of the party receiving the most popular votes becomes prime minister (coallition governments are formed a bit differently, but not much, as the leader of the party receiving the most votes is typically prime minister). Hence, the leader is chosen by popular vote.
Choosing a president by the process we use is unheard of in the rest of the world. It doesn't happen that way.
And you can save the ad homs and lectures. Try being a normal person engaged in a normal conversation. Or are you a dickhead in real life, too?
No, the leader is not chosen by "popular vote"... Parliament rarely has any political party with a majority, they build coalitions. The leader is selected by the representatives and not by the people voting for the leader.
