First off BSD is NOT LINUX! Please use proper terminology and don't lump BSD users with the GNU/Linux projects. We don't get along with them at all.
no - you don't. Most people put the ridiculous platform wars behind them. Most software I am interested in works well on BSD and flavours of Linux so what's the problem?
It's really stupid to not get along with someone because they use a different operating system from you.. You realise that right ?
