Dear Riot: Am I toxic?

I haven't been banned or anything, but I was wondering if a Rioter would be able to tell me if I'm above the average rate of reports. While I'm not using this as "I can afford to be meaner in chat", I want to know if I'm already treading the lines of being too toxic in chat, in which case I'll try to make a more honest effort to think before I type.

I notice that when I talk I can evoke a negative response from my teammates sometimes, and I'm not sure if that's because of me or them.
