Few western countries have a majority votes takes all system, that does not necessarily make them undemocratic. Both Spain and Norway that I know we'll have proportional systems where the number of votes are not necessarily aligned with the number of seats in parliament. A vote in one region might be worth more than another.
Proportional systems are designed from what I understand to balance the power between the populous cities and the country side.
I don't make a judgment call towards if one is better than the other but I do firmly believe that 50% + 1 vote is not a mandate. I would really like to see a proper 2/3 majority before you let someone impose their will on the other group. Proportional representation has one interesting side effect it seems. You get more political parties in parliament leaving lunatic fringe groups their own parties and allowing the centre mostly to rule.

Or you have to put together a coalition to rule which may include cozying up to one or more "lunatic fringe groups" out of all proportion to how many seats they have.
Germany has had coalition governments almost all the time since 1949, and there are very few „lunatic fringe groups“ in parliament. Let alone part of the government.
