From what you wrote, I guess that you get into conflicts with other people or they complain about you. My general attitude has helped me in dealing with all kinds of people. Try to figure out what kind of person it is you are talking to before you say anything drastic. Some people are open and enjoy heated discussions, others (most of the people) are actually insecure about themselves and cannot be confronted head on. Empathy is key to making yourself appear friendly even if you are disgusted by the other person. Toxicity is inherently subjective and it doesn't matter so much what you say but how you say it. I might tell you the work you are doing is crap because reasons. Or I might engage in a brief how-are-you-doing and mention it as a sidenote that I've seen something that looked unfortunate and then ask about YOUR opinion on it and guide the conversation with subtle questions in such a way that you see the problem yourself. Often in bureaucratic environments, when something got stuck, I did not try to tell them what to do or how to do their job. Rather, I would give them the credit of being the "expert" in their field and ask them for advice for my situation. People are way more willing to help you if the idea came from them and they immediately like you if you show them respect for the work they do (that is especially true for hard working but overlooked people, e.g. secretaries, cleaning personnel, etc.). Also, in order to not appear toxic, understand your colleagues' characters, admit mistakes in communication and tell them you are sorry if there was a problem, address them with respect and DO NOT push them into a corner. NEVER become overly defensive or aggressive, ALWAYS be prepared to let someone make decisions which you wouldn't do while maintaining your friendliness. I see it as a kind of diplomacy. As long as you are not the boss, it is not your call to decide who does what. If there's a real problem with a person on your team, your boss should already be aware of it and he should be dealing with it without you having to tell them. If your boss doesn't know the people on his team, then you have an entirely different problem.
