I voted option 1. because he has helped me in this life.
Though I must add to that, because many other people have helped me in many ways, in fact, so many people have helped me, even people that I never met and do not even know that I am here in this world.
So why do i practice Dorje Shugden, I'll add more reasons:
1. Dorje Shugden is the Buddha that I have strongest (karmic) affinity with, everything in my life points that direction, so it is the most opportune Buddha for me to practice. From the first day I saw an image of Budddha Manjushri I knew we were "family", I knew this was a friend. Dorje Shugden is no other than Manjushri emanating in the most suitable way for my mind now.
2. Knowing that, even intellectually only, I must be plain stupid to not practice, not nurture this relationship and put worldly things as more important.
3. Many other beings have helped, me and many many many sentient beings have helped me, but none can help at the level Dorje Shugden can help. When I rely on Dorje Shugden, it is not only that I get help, it creates causes for other sentient beings to establish an affinity, a connection, a karma for them to receive help also, spriritual help. I have a very nice dentist and he has helped me, but I won't call him the day my mother dies, what help would he be then? But when I establish a clean affinity with dorje Shugden, I know my mother will be fine eventually.
4. the controversy is a golden avenue flanked with trees of merits growing, blossoming. The skillful ways of the Buddhas in actions, Manjushri and Chenrezig and their enlightened entourages are simply mind-blowing! This ban is a perfect way for many many many people to connect to. When I see such skillful ways, it makes my faith in Dorje Shugden and in the Dalai lama stronger.
