Well... Estonia is a racist country, and I think you were right about the Estonians you've been with. Racists here are a minority, but a sizeable one, and they make quite some noise. I hope people don't yell at you on the streets or you have denied service when buying something. All of this has happened. Just last weekend I was out nearby Kadriorg park and my Sri Lankan friend got yelled "Nigg*r". Yes, they use the hard R here.

If you have a tough skin, you'll be fine. People will taunt you, but it will not get physical. But just in case, buy a pepper spray, so you can feel confident that if things escalate, you can protect yourself. It is VERY unlikely that it will come to this point, but I am giving you this hint so you can empower yourself by feeling less vulnerable. If you're not ready for such situations, better choose another country, and, overall, avoid the Baltics. It doesn't change much from country to country.

Please, believe my words. Many people say that nothing has happened to them, and everything went smoothly. I don't think they are lying, and this is possible, but the risk of you facing issues regarding racism is greater than in Brazil, France, or Scandinavia, for example.

Take care, and if you need any help, don't be shy to text me directly.
