You're jumping a step here because you're making a sampling error. Like I said before, we know nothing about the distribution.
Let's put this in an extreme example. Suppose there are 100 people. 99 of them have the favorite color green. 1 of them has the favorite color red. Does that mean the logo will be red? What assumptions are implicit here to say yes? (this is where the logic fails) If a singular person controls the color of the logo and that person is not chosen at random then it really doesn't matter how many people have a favorite color green. The logo will be the favorite color of the person that makes the choice. Everyone else is noise.
Coming back to Twitter it would be naive to assume that the choices are being made democratically or uniformly at random. So what does the median employee's opinion matter? We know that higher incomes tend to lean more conservative but this is hard to say here because those studies generally aggregate out all salaries >$100k/yr, which might as well be a random sample. If the trend continues (reasonable assumption, but naive to take as fact) then it is reasonable to assume that managers (who we are assuming make more money than the median employee) are more conservative. But again, we just don't know.
The data you are linking to is actually irrelevant to the conversation at hand (it also has a huge yearly variance, making it even more noisy).

No, this is exactly WHY it is unreasonable. This is how conspiracy theories work. Humans want causal understandings but they have limited information and their imaginations fill in the gaps. If you have little information you should also have low confidence. Look around here at how many people are certain of conspiracy. Look in the Twitter thread too. Much of what people are saying is highly unreasonable and this is not healthy for us as a community.
Is it unreasonable to suspect people on the right are targeted more often than the people on the left? Wouldn't that be the default assumption and the opposite position would need evidence to prove otherwise?
