Findings cast doubt on the existence of Jesus Christ

I highly doubt that. Mythicism is a minority position, though not one without merit, and the article admits to this fact. But it is nevertheless true that the majority of biblical scholars, both secular and religious, believe Jesus existed.

Fitzgerald points out that for centuries all serious scholars of Christianity were Christians themselves, and modern secular scholars lean heavily on the groundwork that they laid in collecting, preserving, and analyzing ancient texts.

That doesn't automatically make the majority position unjustified. It could indicate bias, but you'd have to demonstrate that bias to be justified in implying it here. Additionally, it doesn't mean every claim is taken at face value just because it came first.

Historians are subject to the peer review process, too, so to cast aspersions like this only delegitimizes mythicism, which is already struggling to gain broader legitimacy. This article is trying to punch up but only succeeds in punching itself in the face.
