Formula feeding moms feeling pressure?

Over the last few weeks I have had several people ask me if I plan to breastfeed, when I reply with no, I immediately feel a sense of judgement or I get the "speech" of how great breastfeeding is. I agree that breastfeeding is a beautiful thing and I give all props to mothers who do so. However, I have made the decision that I feel is best for me, my baby and my family and that is to formula feed. 
I just find myself lately getting annoyed or frustrated by the many moms out there that feel the need to "persuade" me to breastfeed. I could care less how people choose to feed their child as it is their decision entirely. And I would never try to talk them into anything different. So I have yet to figure out why breastfeeding mothers feel the need to try and tell me what's best for me and my baby. I guess what ultimately set my off was my own sister in law sending me links to breastfeeding stuff on Pinterest with a message stating how she would hate to see her little niece or nephew miss out if I don't even give it a try, because she loved it so much. I love tomatoes, but that doesn't mean my husband does. What is right for one, is not right for all. 
Has anyone else who is planning to formula feed had this issue and if so, what were your responses when asked if you plan to breastfeed or how do you handle the situation? I know the easy route to get people off my back would be to just say I'm not sure if I'm going to yet or not, but I feel I shouldn't have to lie to avoid judgement. 
And I please ask that nobody reply to this with reasons why breastfeeding is so much better than formula. Positive replies only! :)
