Here is the /r/science thread, and here is my shadowbanned comment. I've pasted the comment verbatim below:

The key question is whether or not the transmission of measles has increased to the point where it may once again become endemic in the United States

Why? The recent 'outbreak' of measles at Disneyland was not only a strain of measles that no vaccine offered protection from, but there were no complications or deaths that occurred.

The mortality rate from measles had dropped to 1-2% in the United States in the 1930s, long before any vaccine. In first world conditions, measles is a "self-limiting infection of short duration, moderate severity, and low fatality," A. Langmuir, "The Importance of Measles as a Health Problem," American Journal of Public Health, vol. 52, no. 2, 1962, pp. 1-4.

The CDC website claims the MMR vaccine gives a lifelong protection against all measles: how is it even possible for an outbreak to occur among the vaccinated then, as we saw at Disneyland? If the MMR vaccine gives lifelong immunity, why do you need to keep getting new immunizations for it?

Meanwhile, 100% vaccination rates for measles will not prevent an outbreak. There is no 'eradicating' measles if only enough anti-vaxxers get out of the way.

Moreso, "with widespread administration of the measles vaccine, we expect that the incidence of modified measles will increase in the future", i.e. the more you attempt to vaccinate the more you will introduce measles into the population. The CDC link on measles notes a resurgence in measles in the 1990s in the US, and this is exactly what we would expect from increasing the rate of measles vaccinations.

In the US, you have a higher chance of dying from the measles vaccine than due to measles.

There are also indications that the vaccine leads to measles susceptibility in children. Breastfed infants of vaccinated mothers have nearly three times the risk of measles infection than those of naturally immune mothers. "Infants whose mothers were born after 1963 are more susceptible to measles than are infants of older mothers. An increasing proportion of infants born in the United States may be susceptible to measles," M. Papania et al., "Increased Susceptibility to Measles in Infants in the United States", Pediatrics, vol. 1045, no. 5, e59, November 1999, pp. 1-6. "Our results suggest that infants born to mothers who acquired immunity to measles by vaccination may get a relatively small amount of measles antibody, resulting in loss of the immunity to meales before the vaccination age," Hong Zhao, Pei-Shan Lu, Yali Hu, Qiaozhen Wu, Wenhu Yal, et al., "Low Titers of Measles Antibody in Mothers Whose Infants Suffered From Measles Before Eligible Age for Measles Vaccination", Virology Journal, 2010.

On the other hand, measles can be treated simply with acute Vitamin A doses.

Given all of this, why are you personally afraid of an endemic measles, and why do you think vaccination is the solution?

As a final question, which measles vaccine do you recommend? The MMR vaccine is currently still being recommended by the CDC. Meanwhile, The US government has been suing Merck for several years in an ongoing private case that alleges that Merck attempted to "defraud the United States through an ongoing scheme to sell the government a mumps vaccine that is mislabeled, misbranded, adulterated, and falsely certified as having an efficacy rate that is significantly higher than it actually is". Although this case has been ongoing for several years, all of the details are closed to the public and concerned individual citizens. Why should anyone take the MMR vaccine until they can see the details of seven years of litigation?

I've posted an anti-vaxx comment and would really like a response. If you'd like to see answers to these questions, regardless of which side of the fence you may be on, please upvote.
