Serious RANT. Don't give me your negativity!!!

I am absolutely livid!  I was at the store today with my 2 month old daughter. I was carrying her because she received shots and was fussy. Plus I wasn't shopping for much so holding her wasn't a problem.  
But back to my story. I was minding my business and a lady with a toddler maybe around 3 approached me and just said typical baby compliments. Like how she is cute and blah blah. And asked if she was a normally fussy baby and I explained to her that my daughter just recieved some shots and was fussy. 
And she said "that's why I'm glad I didn't vaccinate my child". 
Then has the nerve to be upset because I walked away. 
And said I was disrepecting her right to make the decision not to vaccinate. 
And I replied 
Well I have the right to keep your child who could be infected with something away from my child who isn't old enough to be vaccinated for. 
Was I disrespectful? 
So bye. Rant over!
