The motivations of the republicans is a separate issue and has very little to do with whether ID laws are good or bad. Focusing on Republican motivations results in several fallacies.
The argument from consequences or argumentum ad consequentiam if you insist on Latin, is a logical fallacy that the perceived outcomes of a proposition can determine its veracity. An example of arguing from adverse consequences might go like: belief in the theory of evolution leads to eugenics; therefore the theory of evolution is false. Conversely an argument from favourable consequences might go: belief in God leads to an increase in charitable giving; therefore God exists.
The genetic fallacy creates a fallacious argument that is accepted or rejected based on the source of the evidence, rather than on the quality or applicability of the evidence. It is also a line of reasoning in which a perceived defect in the origin of a claim or thing is taken to be evidence that discredits the claim or thing itself. The fallacy is committed when an idea is either accepted or rejected because of its source, rather than its merit.
The genetic fallacy is a logical fallacy but is frequently not a Bayesian one: some sources are so consistently full of it that they reasonably constitute a refutation for all practical purposes. However, that this is a logical fallacy means you will still need to convince the source's fans and bystanders by engaging the source material.
nice copy and past job as a way to obfuscate and avoid the question
The motivations of Republicans in creating these laws is a central component of the discussion
If you want to avoid the topic all together than why don't you just say so
I choose not to ignore the statements by Republicans as to why they created these laws and I choose not to ignore the conclusions of the GAO report on the effect of these laws...which just so happens to conform with the Republicans reasons for creating them
If you want to ignore that or pretend it's not part of the conversation then that's fine with me
If you want to discuss whether bringing up the motivations of the creators of these laws and the consequences of these laws is actually an example of an "argument from consequences or argumentum ad consequentiam if you insist on Latin" then I'll be glad to have that discussion
hint - just because I was talking about the consequences of the law does not automatically make it an argument ad consequentiam
and if you're going to copy someone elses words at least have the decency to use quotes
