So despite his awareness of political and religious persecution and the existence of concentration camps, he lauded Adolf Hitler and his regime.
What he said is not what you were claiming though. People have been aware for years that he made a fool of himself over the Hitler visit, though with the Olympics taking place in Berlin in 1936 you will find he was far from the only politician to visit or say things about Germany that was positive in some way or other, but that does not make him a supporter of the Nazi's or a sympathiser with their policies. As an example, you may or may not like David Cameron but it is almost certain you would share some views with him on certain ideals even if you do not agree with 90% of his policies. Lloyd-George was also critical of Mosley's Black Shirts, a somewhat unusual stance if he agreed with the actual policies of the Nazi's.
What this all seems to boil down to is that Lloyd-George made a visit to Germany and then returned to Britain and said some positive things about Germany at that time. It is the interpretation of these comments that you say indicate he was 'pro-Nazi' along with his long held anti-Communist views. You have no specific example of him actively proclaiming support for a policy by name, or suggesting such a policy should be adopted in Britain, or at least if you have you have not bothered to produce it here so far. Would you agree with this summary so far?
