Java -- while I really hate it's shackles, is designed to keep folks without that constant consideration of every code change, somewhat on the right track.
If you're not carefully considering every code change, then do you just blindly charge ahead, slingling code, and hoping you aren't on call when it breaks?
Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
