The snarky replies are because people are interpreting your questions as challenging and ignoring obvious context. So, they’re trying to shut you down.
A less snarky response:
> do you have more information on this, or perhaps why it is a pillar?
Christianity is referring to Jesus Christ (not his actual name). He was a religious figure and publicly executed. The story of his life, execution and what happens after (resurrection and ascension) are central to Christianity. This is what makes his death a “pillar”. The religions is built on it, like a building is supported with pillars.
> Do other religions not have something similar in their [historical/current] practices?
The “not” in your question implies that it this question is opposed to your last question. That a public death can’t be a pillar of Christianity if it’s in other religions. This is not the case. Something doesn’t have to be unique to be a pillar. Asceticism and isolation are pillars of monastic Zen. They are also pillars of Shipibo shamanism.
So, yes, lots of other public sacrifices. Point still holds.
