I personally do not believe that there is a nigh undeniable link between animal fats (saturated) and colon cancer.
In the recent World Cancer Research Fund/American Institute for Cancer Research report of diet and cancer, it was concluded that there is limited but ...

Studies have suggested that red and processed meat consumption elevate the risk of colon cancer; however, the relationship between red meat, as well as fat and protein, and distal colorectal cancer (CRC) specifically is not clear. We determined the ...

Both of these seem to also posit the same thing.
The issue with colorectal cancer is mainly in food preparation/processing. Something that also ties into the issue of the thread. Hyper processed foods are intrinsically tied to meat and likewise the oils within the processing.
The advent of vegetable oil has been disastrous. But the approach to mitigation must be holistic, meat and saturated fats aren't anymore dangerous than MOST seed oils outside of those cooked above their smoke point.
Then you are a fool, however it will take a lot of effort to convince you of that, and I will ask that you read the whole post before outlining your response. Firstly the most important question to ask in nutrition is when one dietary source is changed, what is its replacement? When people aren't eating saturated fat, what are they replacing it with? Eating is a zero sum game, eating one thing means we are not eating another. I'm sure you can already imagine, but usually the replacement for animal fat is other unhealthy foods such as refined sugar, which is linked directly to colon cancer - so too with alcohol. If this is the case, it is no doubt that looking at studies that only compare saturated fat or animal fat intake in comparison to less intake might bring up non-conclusive results. One of the studies listed in this meta analysis was on entirely smokers, a group who I think we can both agree are very unlikely to have any healthy habits at all, and almost certainly would exchange one bad (SFA) for another (refined sugar, liquor, etc). When studies say "no significance was found", what they really mean is that whatever it is they are controlling for is just as bad as the regular standard western diet.
One of the ways around this is to gather a population of relatively health conscious people who won't simply exchange meat for other bad choices and who also share similar lifestyles, which the best source for this are usually the medical practitioners themselves. The Nurses Study
https://sci-hub.se/10.1056/NEJM199012133232404 is one of the most well regarded studies in the medical field for good reason, not only for the reasons above, but also that medical practitioners both understand the value of what they are contributing to (caring more about their accuracy) and the knowledge of what information needs to be told/remembered for the questionnaire. It just so happens that study has the exact information we wish to learn about. You may browse the results of the link, but the meta analysis you posted (which I assume you read) has also mentioned its results. Meta-analysis are great and at the top of hierarchy for a reason, but we must also remember than quantity of data does not trump quality of data, especially when observational studies are being used, there are many variables to take into account.
Now, I won't just be ending this post on the note of simply attacking the meta analysis, but also I will point out a piece of evidence in my favor. For we should not just look at who is developing colon cancer, but who ISN'T. Comparing African Americans to Native Africans and the risk factor is a magnitude of
50x, I don't think I need to tell you that native Africans are not gorging themselves on meat, in fact they are not gorging themselves on much of anything besides refined grains. Read through this paper
https://sci-hub.se/10.1111/j.1572-0241.1999.01089.x, it will touch on most of your counter arguments. However, if you are sharp you will say that native Africans also have a lower consumption of seed oils, very true, however I would ask you why the Chinese also have much lower rates of colon cancer than the western world while being very well known for sesame and soy oil. Why do Mediterranean countries such as Italy, Greece, and Spain continue to have such high rates of CRC despite preferring olive oil over any other vegetable oil?
I look forward to your response.
