I understand why Turkey is invested in genocide denialism but I've never gotten why it's so much more frothing-at-the-mouth Kill Bill-sirens obsessed with it than, say, the Abe regime.
Because Japanese denial is merely a hobby horse of factionalists within the LDP. The Japanese people as a whole don't really care because it doesn't affect their lives. However Turks (rightly or wrongly) feel their nation's territorial integrity is at stake due to seperatists and irredentists. Also Erdogan uses nationalism as a crux - the MHP is his most useful ally in parliament and they are needed to push through his agenda.
