Internet rules
If poster is anonymous, judge first by avatar and nickname, then content.
If poster is real person, judge their profile picture, name, then compare content to reputation, hopefully to cancel and close tab soon.
If you repost an image or other content someone else made, like Google search engine does, for instance, you must post validation that the act has recently, uniquely, become 'stealing', in contrast to all the other forms of digital copying that make up the internet, to run cover for copyright trolls. Even if there is no copyright claim, no monetary damages, no aim to profit... especially if.
If you know someone well, use what you know to assume their meaning and intent.
If you don't know a poster at all, assume they mean literally exactly what they said in every post, no exceptions, and have not, and will never, change their minds. Assume their words were chosen perfectly to reflect their intent in your language, so that you can assume your interpretation has been flawless. Allow emotional reactions to flow from there.
