### ⭐⭐⭐⭐⭐ Great small locks!
*by I***C on 3 March 2017*

Like the brand, they do a good job.I am a Persian born US citizen, have been living here, along the beautiful beaches of Newport Beach, CA for over 27 years. Contributed my knowledge to new generations of professionals, contributed any way possible to this beautiful country, but I am sad to say that I am leaving United States, because I do not feel safe and I am leaving in agony. When a cashier of the Ace Hardware Store here in Corona DelMar 92625 told me that it is different to be a born US citizen. I do not like conflicts, therefore I am leaving this country to the patriots. My philosophy, Patriotism is the virtue of the vicious. That’s why my parents had to flee Germany before SECOND WORLD WAR to avoid witnessing murders and atrocities done by mad men in the name of supremacy of race and patriotism. I can not believe that I am experiencing the same as my parents. We, people, suffer because of ignorance. We, people, call ourselves HUMAN BEINGS. I assure you that patriotism, tribal and cave mentality makes them totally the opposite. They belong in animal kingdom. Intelligence prevents one from residing in animal kingdom. We, people, make tools to take life, invade countries and commit atrocities. I go back from my father side over 7000 years back in human history. Persians, the early people, the modern human, the true homo sapiens has offered humanity language, written words, science among many other valuable attributions for thousands of years. The Persian empire for thousands of years freed people from tyranny in other countries, never slaved men, robbed countries from their wealth, nor belittled people for having lost in the battle. They were there to free them. Persia gave home to all the people. All faiths and believes could find refuge in that society. culture was raped, silenced and almost destroyed by the hand of Moslems for over several centuries and now it can be witnessed today clearly. Persians were Zoroastrians and followed a very rich but simple philosophy; GOOD THOUGHTS, GOOD WORDS, GOOD DEEDS. That was our religion and philosophy until Moslems came, tried and mostly have been successful to divide and destroy Persians. And now I have to suffer and not being able to live here peacefully where I called home for over 27 years. This is thanks to ignorance which is now being flourished and spread under the new administration in this country. I am just being proud to be intelligent, a HUMAN who calls this planet his home. Greatly appreciated for reading this long story of human struggle. Read some Persian poetry. It’s food for the mind. Isaac
