Except you didn't, actually. You were asked to support a specific claim that you made:

Any journalist that reports something they don't like gets a beating, and if they persist, they're killed.

You were asked point blank by user @Pfhortune -- but you ducked to the side, and put out some noise about there being lots of people with guns walking around. You were then asked again by @runarberg -- but the article you dug up still didn't support this claim -- referring only to a vague "pressuring" of journalists by Hamas, and threats to collaborators. But nothing about specific cases of journalists being routinely "beaten, and then if they persists, killed" (per your words) for saying stuff Hamas doesn't like. Meanwhile the same article mentions far more worse abuses by the IDF (which has apparently killed some 147 journalists since the start of the current massacre in Gaza -- some specifically targeted, some killed incidentally).

In other words -- it looks like you're basically making stuff up here. If you'd care to convince us otherwise, you're going to have to do a lot more than 5 seconds of Googling.
