The reality is that the only reproducable, controlled, fusion reactions mankind has managed to generate in a reproducable manner consume much more power than they generate, and are many, many years before becoming a source of power.
Regarding fusion by-products, the fact is that most fusion reactions produce deadly forms of radiation, weather "cold" or "hot", and the fuels required for a-neutronic reactions are not in infinite supply.
Granted that the idea of "Mr. Fusion" powering our automobiles on flat beer with helium, water vapour, and heat as it's only waste is captivating. Having a near infinite supply of energy would solve many of our and the world's problems (and I'm sure cause many of it's own as well).
We should not lose sight that there are real, proven sources of energy that are renewable, cleaner and longer term than fossil fuels, that also require our investment of research, money, time, and education. Although they are not a "Magic Bullet" like Cold or Bubble fusion, they are the reality we should be focused on.
