As with many things, there are points of view based on good foundations and points of view based on unsound foundations and whether we agree with them, or, not, there is a time to hold your council and a time to voice an opinion. There is also a way of voicing those opinions without upsetting your listeners. Equally there is a polite and impolite way of receiving those views. I fear that the skills of knowing when to keep quiet from any point of view and perspective is on the wane.
