A logical fallacy does not automatically render an argument invalid.

And... scene. Thanks for reading.

I consider this the distinction between logic and reason.

But it does make me much less likely to give the argument any further consideration.

i think this complex chain of claims suffers from ambiguity as to what constitutes "an argument"

a logical falacy, to my mind, does render an argument invalid, but not necessarily all arguments presented; often, many arguments in favor of a point are presented as part of an overall discourse, and it does not render the discourse invalid.

It most definitely renders a well-formed argument invalid

It makes the argument invalid because the reasoning is wrong.

The claim may still be valid.

A logical fallacy merely means that the conclusion did not follow properly from the premises, that is like saying the earth is round because the moon is round

The presense of a fallacy renders the argument invalid, regardless of conclusion or premises.

However, the presense of a fallacy does not automatically make incorrect the conclusion wrought by the argument.

If your best friend Billy says to you, "My uncle was killed by a falling tree, thus all trees are evil, murdering scum," you can demonstrate that they are making a categorical assumption.

This does not mean that trees are /not/ all evil, murdering scum; it just means Billy made a mistake in his reasoning, and should not arrive at that conclusion using only the proferred faulty argument as the basis for his belief.
