My own opinion is that the role of government should be mostly limited to common defense, ensuring essential infrastructure and enforcing/resolving legal disputes. Essential infrastructure should include banking and internet access at this point as it's nearly impossible to function in society without them.

Infrastructure providers should not be able to refuse customers engaging in lawful activity. Your phone company can't shut you off because you say, "I wish $POLITICIAN were dead." You don't have to like or agree with everything everyone says, but it's a very dangerous slippery slope.

Personal liberty should be maximalized so as not to infringe on the rights of others. You do not have the right to live a life without risk of being offended.
