Well first off you took one section of a collective, which are all intertwined, not to mention the articles, one of which explains Trump is now eating healthier.
Secondly, by asking how unhealthy can it be, I'm clearly implying it's unhealthy, but how destructive is it exactly is the underlying point. Which would mean it's unhealthy to some degree, but whether it's slightly unhealthy, or horrendously unhealthy, is the question.
Thirdly, as this is part of what was said prior, these stars do not necessarily want to promote the product itself, or care about the product at all. If people choose to stuff their faces and sit on their butts all day, it's their fault for what follows. You shouldn't eat lot's of fast food if you can't burn it off, whether that's natural or through exercise, just like how you shouldn't go out and purchase a bunch of luxury items through credit if you don't plan to pay them off, naturally or though extra work.
Okay, thats a little more reasonable than what it sounded like you were saying. That said, I still find this whole discussion to be fairly strange. Why anyone felt the need to bring up Trump's eating habits in response to the Barr debacle is beyond me, but you do you.
It started off with a Rep member not taking the Barr thing seriously. That led to the Dems 'rubber' chicken nonsense. The KFC reminded me of Trump.
Plus I've learned over the years that people who may be in a box, are hard to explain to, whats outside the box, by only using whats inside the box. Trying to merge them tends to be the best approach, but doesn't always work, and sometimes I can flat out go overboard. What I've also learned is that understanding things isn't as simple as just being young and stupid and not getting it. Aside from the brightest of minds, most people require building blocks to get out of the box and understand more complex concepts. If you're never given or exposed to those blocks, you will have a hard time moving forward. While I don't try to 'teach' because I'm certainly no guru, I do expose others to my way of thinking indirectly, assuming they may catch on, just like how I pay attention to them and try to learn from where they're coming from. That doesn't mean I want people to think and be like me, but the more building block understanding people have of each other and life overall in general, the better and more meaningful the conversations should be going forward.
I find the simple 'my sources said this, and your sources said that', arguments to be boring and useless for the most part. If you can't go beyond that and dig deeper, it's something you should look into, if you really care that is. Just think about what the deeper understanding of science has done for the world for example. I don't mean "you" specifically either btw, just people in general.
