I think possibly you are being a little over-sensitive. While we have rules regarding abusive language, and we do enforce them, we are ever-mindful that racing in LFS - despite the fact that it's virtual, not real - can be quite stressful. Adrenaline flows and tempers fray. We're complicit in creating that environment in the server, with regimented race restarts and a competitive and extended goal-based environment.
What we would act against is vile or profain abuse, or patterns of malicious behaviour over extended periods, eg: premeditated harassment or bullying. We're less likely to directly act against off-the-cuff biting back or throw-away comments that are clearly attempts at saving face. Typically they're tantamount to acknowledgement, by the person responsible, that they screwed up and don't have it in them to admit it and take the blame for whatever the argument is about (usually a failed and foolhardy attempt to overtake etc).
If you're considering filing a report, give thought to whether or not the above is the case. If it's habitual use of foul language or bullying, excessively aggressive demeanour etc, feel free to file and we'll warn the individual responsible about their behaviour if we agree. If it's a one-off bite-back then perhaps just nod and say to yourself "yeah, you're right, you did screw up" and otherwise let it slide.
