This is where a strawman has entered the conversation.
You agree that mental health issues and drugs play a huge role in the current societal crisis this country has BUT, Republicans are bad because they 'oppose' all help for that. Where exactly is this based on? and if Republicans are opposed to this, they shouldn't, no one should. We agree on this, no Republican is opposing this in these forums, so can we stop and just say we agree that this situation should be improved? can a.net do this?
Let me just say, as a conservative who votes GOP, this problem is a problem of society as a whole, entirely, not of one party but both parties, of all people involved at policy making and governing.
We have gone down this path for far too long, and there isn't much will among anyone to address this. That's why these shootings and violence has been happening all these last years.
Drug epidemic, fatherless and broken homes, mental health issues are a huge problem currently in the US, and they are issues not being seriously addressed by neither party.
Its simpler to blame it on a gun, rather than the root of the issue itself.
Guns have been around for far too long, and its been these past 20 years mass shootings/killings have spiked. Clearly the problem lies in part somewhere else too.
Yet another attempt at deflection.
All the systemic problems you mention may well increase the incidence of gun violence, but they mostly stem from a society that drives ever larger inequality, pushing poorer classes deeper into helplessness, away from the means to alleviate their issues (lack of healthcare and education access among other). It promotes the use of drugs, mostly enabled by pharmaceutical companies which make fortunes selling barely regulated opioids.
I find comical the idea that you pretend that these issues are 'not being seriously addressed by either party' when, for a start, every bill trying to promote better access to healthcare for every American has been systematically voted against almost exclusively by the GOP.
Here is a list of house votes for major health reform laws in the last few years, and who voted for/against them in every instance... I think you'll basically see a blue and a red column every time, the red one always standing for the position that would prevent more 'socialised' access to healthcare.https://www.healthreformvotes.org/
The US has devolved into a predatory capitalistic system which leads to increased inequality. You're right in one aspect: It's a systemic issue that certainly has consequences when it comes to gun violence. It is no wonder that shootings have increased as lower classes find themselves ever poorer and more desperate. Politically, however, there is only one side of the spectrum that continually votes to maintain and further that predatory 'every man for himself' system, and it happens to be the same one that also votes to repeal any sort of gun control...
It IS a political issue. A very fundamental one at that.
