If your goal was to present two contradicting statements then you're not looking at the wider context here.

The "Anti-SJWs" generally believe: "Jokes shouldn't be taken seriously and should be left alone and not be taken down for being offensive."
The "SJWs" generally believe: "Jokes despite just being jokes can be innately offensive and harmful to certain people and should be taken down."

In the first example the "Anti-SJW" is calling out the "SJWs" for not getting offended by this post because despite being a joke, it is also offensive so it should be taken down like the "SJWs" say.

In the second example the "Anti-SJW" is standing by their proposed idea that jokes are jokes and should not be taken seriously, so they will defend it despite it being offensive.

Also, the reason why you're being down voted is because most people don't really identify with these kind of posts, and honestly find them obnoxious, be them "SJWs", "Anti-SJWs" or disinterested bystanders.

1. 1804 Haitian massacre, when the island's entire white population was killed. Soldiers would go into families houses, torture the families, rape the women, and killed everyone. They started with the men, with the soldiers being hesitant to kill the woman and children. They did anyway, in time. They offered amnesty to all the whites who had hid from the initial attacks, then murdered them when they came out of hiding. Most of the survivors were white women who were placed into force marriages with black people to eradicate every trace of whiteness from the island. The death toll was in the thousands, it doesn't hit numbers as high as the Holocaust, but lets not pretend like no white man has ever been killed for his skin color. Even those who were kind, supported the black population, or were against slavery suffered the same fate.
2. They are calling out hypocrisy. If Liberals are against the "Kill the Jews" statement, they should be against the "Kill The White Man" statements too. If they don't, they are hypocrites.
