I think your opinion is heavily influenced by American politics and doesn't align with how parliamentary democracies work.

If Parliament is "we the people" and they vote to make decisions on every aspect of governance as your representative, how come them electing the Prime Minister is so offensive to you?

You shouldn't even really be voting purely along party lines, you elect your local representative and they represent you. You should evaluate them on their own merits. They often vote along party lines, but even if "your party" wins your local election or even the most seats that doesn't mean they get to form government without the support of a majority of Parliament. It's always been this way, at no point do you ever make a direct decision on who leads.
