Same as you as a human being and especially a public person, leader, author deal with any criticism.
More popular you will become more "attacks" you will face, deal with it. It is impossible to satisfy everyone's interests. When one group will like your specific decision, there always will be another group which will not like it. It's a life. Be calm, have clear mind and keep controlling yourself, your thoughts and your actions. If you will have any problems here, practice Mindfulness, Meditation, Qi gong, Tai chi, Buddhism, whatever you will like.
Never waste your time and energy on someone, something what does not matter to you and does not gives anything. If there is a clear discussion and arguments provided, then it is good, if it is only aggression, then never react, immediately ignore and delete.
Whatever other people say to you - should not bother you, you don't have to do anything. If you think it may be somehow true or information was helpful - thank person for his time, lesson, feedback. If there were 0 useful information, just ignore. Life is too short to waste it reacting on every stupid thing and dump person.
Don't expect anything from other people, even from yourself. Never surround yourself with people you don't want to be with every day, remove them from your life asap, instead - surround yourself only with smart people who can give you any benefits and make you better as a person.
