Being aggressive, brave, feeling privileged, or whatever it is that makes me speak out in almost any circumstances doesn’t actually correlate well with knowing things useful in a discussion or in having ideas of value to a discussion. It’s worth some effort to me to avoid driving away people who have stuff to contribute to the discussion even if they are “timid” or easily scared off. Brash, outspoken people don’t really lack for opportunities to make their points; but we don’t have “all the points”.
