The nature of narrow and of overly broad definitions without sufficient information to really evaluate the data presented can lead to false conclusions, like the hammers vs guns meme. Once these things become part of the larger conversation they take on a life of their own, factual or not.
Take, for instance, the 20,000 gun laws truism. The Center on Urban & Metropolitan Policy did a study titled "Twenty Thousand Gun Laws" (it was in another DU post) and found there are closer to 300 State and Federal laws. They were careful to define gun laws for the purpose of the study as "laws pertaining to the manufacture, sale, purchase and possession of firearms" and to acknowledge there are other laws not germain to "gun control. Texas, for instance, has a surtax on a number of sporting items including ammunition for the purpose of funding Texas Parks and Wildlife (Perry raided the fund to support a fictitious surplus, but don't get me started . . .).
So, while I do not doubt the veracity of the data provided I don't think there is sufficient information to fully digest it and draw useful conclusions.
Sorry to be picking at nits, but it's a habit I picked up in the Gungeon.
