A lot of the things you're complaining about have been established practice on HN for many years. If you want to learn how HN works, I'd be happy to help with that. But it's time that you stopped posting off-topic complaints and trying to stir up drama about these things. 18 of these comments in one thread is quite enough.
All I am saying here is that if some statements can't be read, others can't read the argument. An argument where others can't read one side's statements is not an equal argument. You must at least be able to make every comment you have conversed with readable. Otherwise it is just your speech.
One of the settings is “show dead”. You can toggle that to yes.
Now you will be able to see all “deleted” comments. Both yours and the ones from others that were “deleted”
