To disagree is not to hate.
Flipping this around, to love is not to agree.
Negate these two statements and we have something sounding like Orwell's "Ministry of Love."
DISAGREEMENT IS HATRED
LOVING IS AGREEMENT
Resist these untruths. You will then be swimming against the flow. If loving was equivalent to agreement, then no one would love anyone.
As clear as this is, few live these things out. And that is at the heart of political tribes (see esp. Amy Chua) and identity politics (see esp. Jonathan Haidt).
This is soft totalitarianism (see Rod Dreher), akin to Orwell's "Ministry of Truth" in 1984. Which simply declared, expecting no resistance:
WAR IS PEACE
FREEDOM IS SLAVERY
IGNORANCE IS STRENGTH
