No, moderatism or centrism is legitimately a fallacy. The idea or intuition that, given two endpoints, the most correct position is one in the middle, is a fallacy. It depends entirely on the endpoints.

For example: the three fifths compromise. Turns out, bad. The correct answer was emancipation all along, and the 'centrist' answer was just bad. Because, well, one of the endpoints was slavery. If you 'halfway' slavery, that's still bad. There's no merits or 'well what about's when it comes to slavery.

That doesn't mean centrists or moderates are wrong - they're often right. But it DOES mean that just taking a middle of the road approach isn't reasonable. You need to actually understand why you're doing that, and why the middle makes the most sense. In some parts of the world, right now, as in right now right now, the 'both sides' argument is pro-genocide. In the past it's been pro-slavery, pro-colonialism, pro-holocaust, whatever. Plenty of really bad stuff.

So, you can't hide behind 'both sides'. You need to justify WHY 'both sides' and why in the middle is best for this particular case.
