Firstly no there is no argument to be had on the environmental side or on the ethical side when we're referring to factory farming.

All meat doesn't come from factory farms, and that is a separate discussion. On the flipside, industrial plant farming is also of high environmental impact.

On the health issue, did you even read source [2] before pulling me up on that?

Yes. It's not a very good source. It's simply a journal, it's not peer reviewed, and it doesn't even support your post.

In high-income Western countries, large prospective studies and meta-analyses generally show that total mortality rates are modestly higher in participants who have high intakes of red and processed meat. The strongest evidence of a specific adverse effect is the increased risk of colorectal cancer with high intakes of processed meat.

They are lumping in processed foods - hot dogs, lunchmeat, preserved meats, and other highly processed and items - in with unprocessed meat.

That's garbage science.
