Investing is hard when you have rules to follow

How many of you have some moral grounds when you invest? Investing is hard when the companies you invest in cannot be involved in some specific moral rules which you have decided for yourself. Eg I do not invest in companies whose primary business is in the killing of animals, eg a slaughterhouse or whose business creates weapons which are used to kill. Eg gun and weapons. 

Well for me I believe what you do in every aspect of your life should correspond to your beliefs if not it will be hard for you to reconcile with your inner self. Well that’s just me.
