Trump's entry ban - What can we do as individual academics?

There is world wide shock, protests and discussion about president Trump's entry ban for Muslims from some seven Middle East countries. While the justification given for this measure is the prevention of terrorism in the US many academics and their professional associations as well as universities are protesting this ban pointing out what this means in terms of human rights, international collaboration and individual academic freedom, see for example http://news.stanford.edu/2017/01/28/community-letter-stanford-leadership...

Some universities do not just protest but have started to take concrete action, see for example the initiative taken by a major Canadian university, http://president.ubc.ca/featured/2017/01/29/statement-in-response-to-u-s...

What can we do as individual academics?

Some colleagues have suggested not to attend, until the ban is lifted, any academic and professional conferences in the US in order to demonstrate solidarity with colleagues from the Middle East who are banned from entry.

However, many are not sure and argue this would 'punish' the wrong people and these conferences would provide visible platforms of protest and resistance.
