Ad hominem is to attack the persons character. I clearly stated that your logic is squirrel shit.
Any parties manifesto in the majority, will be about internal politics, but those policies will ultimately impact their relationship with external countries and shape what their foreign policies will be. You would have to be a fucking imbecile to think otherwise. (Again, not an ad hominem before you start wanking yourself into a lather)
Reddit admins have already put things in place to counter editing or deleting comments.
I deleted an account from 2011 yet when I searched on Google for “site:reddit.com account name”, it listed loads of posts with their previous content (I used the script that changed all the contents before deleting).
All SM sites have been doing this for a while: they’ll shadow delete your account but will retain all the data.
