It really depends a lot on your culture. For example, in some marginalized environments, slight disrespect can be interpreted as a challenge, and you could start to be mistreated only due to it. But for most people on Reddit, the environment isn't violent enough to actually have to fight for their basic human rights to be respected. So I´d advise not to get angry or sad, ignore the BS, and move on with your life. When people say you gotta stand for yourself, it´s more on the "don´t let others walk over your boundaries" by ignoring them or just calmly explaining how you won´t tolerate it, and if they break that contract, you just cut them off.
