I sympathise with you for wanting to be safe and free of harrassment. But be aware that riding across an intersection in the crosswalk may put you at risk, especially if you enter the intersection at riding speed and not walking speed. Drivers turning right watch for pedestrians and either zoom ahead of them or wait and go behind them, and in either case, they can judge the pedestrian's pace and avoid hitting them. But a bike comes out of their right rear blind spot much quicker than a pedestrian and they may cut you off or hit you because they just don't see you coming.
