the percentage of people you are referring too is so astoundingly low that I don't think it can be used in this argument. this argument is directed towards trans gendered people. in my opinion if they have gone through the transition and then have no a penis or vagina depending on the person. I don't care, do what you must. but if you are a fully grown man with a penis and testicles that just wears a dress then no you shouldn't be able to walk in wherever you so please. and even people in the trans community vs the amount of non trans peoples is astonishingly low. so low to a point that you are putting the majority of people at a disadvantage just to please a VERY small minority

do you have any factual evidence to support that giving a child all the vaccines at once is harmful, or connects in any way to autism?

no, regardless of the vaccine there is not evidence to support in any way that vaccines cause autism. vaccines have no direct correlation to the way the mind operates and that's what more people need to see. vaccines help the immune system attain immunity to disease by using the disease as a catalyst. its why parents would force their kids to contract disease so they can get the same results. vaccines not only do that job better and faster, it saves kids from having to actually deal with the symptoms of that disease. when you look at what autism is, even if we don't know much about it, it is a mental disorder, autism has no direct connection to the immune system. autism effects neural transmitters and receptors among other things. unless it was a vaccine developed to combat mental illness (in which there is actually no vaccine for mental illness) you cant connect the two. there is without a doubt no connection to autism and vaccines.
