by being anti china, you just contribute to there being more objectionable issues for you to be anti china about. Focus your thoughts, visions and prayers on positive outcomes for all tibetans and chinese and that is what you will contribute to bringing about. By drawing attention and focusing thought on all the negative, you reinforce it.
better to be positive for change than negative about what is.
I am optimistic that you will learn that speaking up can lead indirectly to the endorsement you so fear. Bring your message, but learn to direct the resulting action to be one of positive thought, not more negative.
