That isn't my intention at all. English is not my first language so it might not help but please bear with me.
I intentionally said "I really want to scream" and not "Let me say" because I certainly do not want to be hostile. I shared the point of view of the person I responded to, so no, I really did not express hostility but an invitation to understand that some people actually are giving up "their own personal comfort or lifestyle for the sake of the plane".
>I don’t know how to say this politely.
Look, you're writing something very similar to my "I want to" with this "I don't know but". I'm sure we both have good intentions.
> You’re not a good advocate for the political process if you can’t calmly discuss the opposing viewpoint.
I do not pretend to be a good advocate here. I'm trying to have someone consider that the actions of others are sincere. That people are actually fighting and giving up comfort (which the OP comment denied). I don't want to complain because I'm well off myself (good job, very secured financially, etc) but there are so many people who would not act if we keep denying the possibility of change and insists in making other choices non-existent or insincere. That would have be the case a younger me, that's why I'm quite emotional. It's just my feeling and I understand that it may not be welcome.
>At no point did you provide evidence that a political solution is viable.
Again, that's not my point. I could comment on that, but I reacted to the assumption that "No one wants to give up their own personal comfort or lifestyle for the sake of the planet". This is a very bad starting point to discuss this because the last decade of my life shows the contrary. I only complain that stating the contrary is false (logically) and morally wrong (who can speak for others about their intention?). Why do you think I'm a martyr? I certainly don't feel like one (again, I live in Paris and have enough time and resources to care not about my personal situation but climate change and poor workers who can't bear taxes). Nor do you I want anyone to be a martyr because I know we would have a violent regime change (probably not for the best) if people start feeling like they would have to die to be heard.
