Guys, chill.
If someone makes a snarky comment the best thing to do is ignore it. Sometimes people just had a bad day and it shows (it has happened to me too).

Many many many decades ago when I was in High School, we had an English teacher who taught us an old English poem. It was called "The lament of Deor" and was thought to have been written around 856 (my High School English class was much later than that). It was a list of people who endured misfortunes. The stanzas told of the misfortunes and ended with the refrain "Þæs ofereode, þisses swa mæg", which basically means "That passed away, so may this also". (The character "Þ" is called a thorn, and is pronounced "th". In later years it was written something like a y [which kind of looks like a thorn coming from a branch], and so when you see a sign that says Ye olde pub, it is pronounced "The old pub"). (https://en.wikipedia.org/wiki/Deor)

Anyway, it has stuck with me, so if I run across something that doesn't quite sit right, I just remember that refrain and let it pass away.

I am not convinced that filters protect lenses from impacts. If an impact breaks your filter you have a lot of sharp pieces of filter sitting on your lens. You could see damage as a result of cleaning the splinters off the lens.

I am convinced that filters protect lenses from low energy environmental hazards like blowing sand and salt spray. Impacts are another class of damage. After all, an impact could damage the threads on the lens and filter making it difficult to get the broken filter off the lens.

I still believe that a good hood or a lens cap offers better protection against impacts than a filter.

BUT my study shows that a filter won't do significant damage to the image.

My study was not intended to encourage you to use a filter as all-purpose protection without other protective devices.
