What? If I call someone a thief, I should be able to point to something they stole.

There is a big difference how one acts in a court and in real life. The original statement could either be a slandering (hard to know what they get to gain from it) or its their bitter experience/perception that they feel strongly about, are are sharing on a platform like this.

sandeepkd is an idea thief. Also, he is short guy but walks with high shoes so people will think he is tall.

In a court of law sometimes. In the real world some facts have verifiable proof but the majority have little if anything that can be shared publicly or exists.

If someone called my friend a thief and couldn’t even point to what they stole, I’d mercilessly judge them even outside a court of law. That’s a serious accusation. Going off vibes is totally inappropriate.
