canon does exist and it IS important to me. Anything that has aired on TV or been onscreen in a movie is the simple definition, but to me it is NOT that simple. Since there have been tons of minor contradictions in Trek on various topics I ignore those as details too small to care about.
We know what Picard's brother's name and his nephew's name as well. If some writer were too lazy to look up those details and created new names, I would get ticked off. We know many details like that, that are pretty clear and easy to look up. Whether Kirk can drive a car or why can Data remove his emotion chip when he can turn it off, those types of issues may be fun to debate, but they are not canon issues to me.
