First, your figure for deaths from car accidents is either meaningless (because you don't specify the time period over which the "1.3 million" deaths occur), or absurdly exaggerated (because the annual number of deaths is much, much less than that).
Second, who are you to tell people what they should be concerned about?
Third, you have not demonstrated that the concern most people are showing for the families is politically motivated because you have not supported your reasoning with empirical evidence. You are merely speculating.
Fourth, your calculus for how much you feel others should be concerned about things is overly simplistic. For one thing, you again fail to provide empirical evidence that those responding to the family separations are not responding also to other matters, such as suicides.
All in all, your argument fails.
I forgot to include that the 1.3 million figure is referencing the global car accident deaths per year. The point was just to pick a large number to demonstrate how much more significant certain issues are.
Second, who are you to tell people what they should be concerned about?
Who are you to tell people whether they can tell people what they should be concerned about? I'm a human being with opinions and so that gives me the ability to comment on what people should or shouldn't care about. I'm sure you and many others think we SHOULD care about migrant family separation. Anyways your whole point here is a red herring fallacy.
Third, you have not demonstrated that the concern most people are showing for the families is politically motivated because you have not supported your reasoning with empirical evidence. You are merely speculating.
I didn't claim that most are concerned about migrant family separation because they are looking to score political points. I'm sure people are genuinely concerned. This is a straw man. I said it was politicized, meaning that CNN and other news organizations as well as democratic leaders in the house and senate were using it to score political points. This got it hyped up and in the attention of the public eye. It was a very convenient tool to blast Donald trump on his aggressive immigration tactics.
If you want evidence that family separations are more prevalent, I could get you the recent number of google searches for migrant family separation vs suicide. Furthermore, you can absolutely look at twitter and news outlets and clearly see the focus is on migrant family separation, and not on vastly more important issues like cancer, or suicides, or a plethora of other things. You can also just look at how many news articles have been posted recently about it. I'm not going to be able to get you some peer reviewed paper though, but we can make a reasonable conclusion based on the social media footprint. I'm not saying this would be certain proof, but any reasonable person would accept that currently, the focus is likely on migrant family separation. Its a fad.
Fourth, your calculus for how much you feel others should be concerned about things is overly simplistic. For one thing, you again fail to provide empirical evidence that those responding to the family separations are not responding also to other matters, such as suicides.
I didn't claim it was a bulletproof calculation. It was a decent approximation to show the relative importance generally speaking. I actually even gave a justification or why it wouldn't be that simple by specifying that migrant family separations have less impact than deaths. Regardless, they also certainly aren't responding to other matters proportionally as much. If you look at twitter posts regarding suicide and twitter posts regarding family migrant separation for example, you will see that migrant separation is much more popular currently.
I just don't see any justification why we should care about 3000 people when there are millions dying. THe millions dying should take priority.
