The main problem we are solving is that exposure to aliens would likely cause panic among humans and this may lead to chaos and wars.
Consider that while some ideas have troubled way of acceptance, other ideas of similar kind often become accepted without much ado.
Here is an example. Transposons are extremely important in human genome. Paradoxically the research of transposons is not funded and not much research of them is done. Scientists feel that this is a prohibited topic and avoid it because touching prohibited topics often leads to loss of funding. I believe the transposon research is secretly repressed because they may reveal something important related to transdimensional properties of our DNA, or mind control, or both. siRNA had similar properties. This topic was also poorly funded and it violated the status quo of the molecular biology at the time. Many scientists studying siRNA were underfunded and had trouble in their careers. The situation changes quietly and quickly to better, when siRNA was discovered to have commercial properties. Tools were developed based on siRNA which are used to silence genes for experimental purposes and nowadays also drugs are being developed based on siRNA. Many of biologists didn't even notice how siRNA became accepted and that it produced quite a revolution in basic biology of genes. Essentially a radically new regulatory pathway was discovered which could explain much of cell logic unknown before.
The conclusion from this example is that sometimes some things are taken easily and painlessly if they are commercially successful. Same happened to Beatles. They would had have little chance of transforming the world if not commercial success. The old society didn't want them, they brought the vibration of freedom and were deadly to many values of the old world. But it was commercial success of their records which made their cultural success possible. Alternative youth voted with their money and this decided the case.
It is not clear why the establishment hadn't killed the Beatles earlier. Most likely they didn't realize how Lennon would evolve into a peacenik and a thinker. As Beatles were becoming popular, their texts were benign; it was the music and the spirit of the group which was transformational. The establishment typically is a very poor in arts and they just missed the musical aspect of the transformation. In the tightly mind controlled society, music was a back door which happened to be not guarded too well. So in the beginning the establishment didn't realize that Beatles are a threat for them. Later, they possibly were not killing Lennon because this would have made a martyr of him and only strengthen his message. They only became bold enough to kill him when two things coincided: Lennon became active in peace politics and the attention of masses was distracted from him by the real danger of World War III. And it so happened that the death of Lennon was noticed by many but didn't cause much reaction in the public.
Similarly, the deaths of Vysotsky and Galich have not create much reaction.
In conclusion, I wonder if there is a possible solution to legalize your existence and presence in similarly non-traumatic way. Aliens are already a part of our culture: there are many movies about aliens. Many people grew up admiring Star Trek, Doctor Who and Twilight Zone. Maybe there is a way to make the idea of aliens commercial and have people vote for it with their money. So far it happens a bit too slowly. Books of channelers and ufologists are commercially available, but their sales are limited. We need aliens to become a fad (really popular). Maybe some cultures such as Russian, Spanish, Chinese or Hindu are more suitable for the contact? Hindu are very open to the idea of aliens due to their religion. Think, maybe you can become a common place in India and this makes a smooth entrance to the rest of the world? Suppose, you bring some medical technologies or other technologies which could become viral commercially?
Understand, that at this time, YouTube and movies are of greater influence on humans than books. Books are still a great resource for researchers, but masses are educated by news and movies. Alternative culture is now sharing the knowledge via YouTube.
Here I will attempt a very brief superficial review of relevant channels on YouTube. My list is incomplete and unbalanced, you will find much more, but I want to make an initial introduction to alternative YouTube channels and highlight some basic observations.
