However, in my country, where we use FPTP, we have frequently got extremist parties in power. If seats had been given proportionally, they might not have got power, or would have to operate in Big Tent coalitions.
In the last general election, 486(!) parties fielded candidates. Of course, most of them would not reach the threshold for representation in PR. But some of them will. That would almost always cause hung parliaments.
Upside is, minorities like Muslims will get better representation. They are heavily underrepresented in legislatures due to their dispersal.
