You can't sue everyone that you disagree with. Lawsuits are a huge drain on time and resources - they have their limited places (we have too many law suits now) but I agree with those that say this is not one of them.

Decide what you want to do with your life and stick to those goals. If that's too ambitious a decision in high school (was for me, I had no idea) , decide where you want to pick your battles (another great suggestion from above) and don’t let idiots, morons, racists, anti-Semites change your path. Continue to speak up for what is right but carefully decided where the line is between speaking up and fighting where you won’t win and it will hurt you.

However, your intensity is so strong on these issues, you might want to focus your future in fighting via the political process.

Bottom line is, don't get distracted from your larger goals. Use your energy towards that purpose and you will be more successful.

Best of luck in whatever you decide to pursue.
