The basic message being:

If you are going to boycott any company, do it for specified verifiable reasons. Not because of urban legends or personal desires.

A paradoxical thought. Based on Brother NM's post, boycotting Coca-Cola could be seen as supporting Israel.

Learn the true facts before acting and once you have verified the truth, ACT.

But, in all instance learn the facts and not rely on the word of friends, relatives, "authorities".
