The fact is that de facto and de jure one party states are the future of the entire world:
- PRC (CCP).
- Japan (LDP).
- Singapore (PAP).
- Russia (United Russia).
- Turkey (AKP).
- Thailand (military/monarchy together).
- Burma (military in collusion with political parties).
Etc.
The Chinese criticisms of party politics were always bang on - it purposefully divides and turns societies in against themselves. In heterogeneous societies like Turkey and the US this makes things even more fucked up and dysfunctional than otherwise would be, since the party politics is compounded with another layer of dysfunction of racial/ethnic conflict.
Erdogan is only taking this to its logical conclusion. Liberal democracy is hopelessly flawed, it continually produces low-trust, low-confidence governments whom everyone hates and who can't do anything meaningful. It corrodes law and order. It depletes the capital stock of a country through reckless economic policies like encouraging mass immigration.
It's a terrible system of government.
If you want to oppose Erdogan, then at least come up with something meaningful in his place. Even if it's just straight up military rule, because liberal democracy simply isn't working anymore. Anywhere.
