I'm starting this thread as I observed this bizarre behavior at some forum users.

Context:

Case 1
- user A distrusts user B
- user B has a connection of any kind with user C (let's suppose they reply to each other in different posts in a respectful manner, or user B gives merits to user C)
- user A has no conflict / dichotomy with user C
Result: as a "consequence" of step 2, user A distrusts user C as well.

Case 2
- user A has an argue with user B
- user B has a connection of any kind with user C (let's suppose they reply to each other in different posts in a respectful manner, or user B gives merits to user C)
- user A has no conflict / dichotomy with user C
- as a "consequence" of step 2, user A extends his antipathy to user C.

The transitivity is a fundamental characteristic of mathematics and logic. Thus, if A = B and B = C, then A = C. However, this rule doesn't apply to people.

Explicit context:
Case 1
- Timelord2067 started distrusting nullius 5 weeks ago, according to loyce.club; at the same time interval, nullius started distrusting Timelord2067 as well
- nullius has a connection with me (he merited some of my posts; I translated some of his precious work in Romanian; we talked to each other in a friendly / respectful manner in various topics etc.)
- Timelord2067 and I never had any conflict; the only time when we interacted was in a friendly manner, in one of my topics, when he also merited me
- Timelord2067 becomes aware of the connection between me an nullius, seeing we respectfully talk to each other (also in the above mentioned topic)

Result: Timelord2067 starts distrusting me two weeks ago. I tried to PM him, telling him that without trying to change his opinion (which I was not), I only kindly ask him to explain his decision. Why? Of course, he didn't answer, as he was embarrassed (most likely) to admit that his judgement is "if A = B and B = C, then A = C" and that he applies it to people as well.

Besides, it seems that a similar thing happened also to Timelord2067 and he didn't appreciate. Now he is doing the exact same thing to others. There is a saying in Romanian - "don't do to others what you don't like". I guess he didn't know it.
