They're only warning that your comments about this accident seem to be politically motivated, so that they should be taken with a grain of salt.

you dont look so...

Bring up unrelated accidents strikes me as not being completely honest. Why you didn't mention that what you are talking about is a different train network where the accident was today?

Maybe because it would make your point very weak, and you know this. That's why you seem "not relaxed".

Source of you being intentionally misleading? Sure: https://news.ycombinator.com/item?id=46675778

> Is showing that the government is underfunding railways being misleading?

When the accident happened in a different rail network than the one you're highlighting as being underfunded, yes, of course. In what world wouldn't this be misleading?

Not even our shit TV networks does stuff like that, and they're generally very quick at being partisan and misleading.

In a world where there is underfunding in all railway networks, both Cercanías and high speed railway (other thing is that you don’t want to see it).
