“But nobody is going to jail for their heretical opinions.”
This is not true. You don’t have to look hard for examples of people being jailed in the US for holding unorthodox positions.
Defining heresy as “a position they damages trust,” implies that an accused heretic is at fault for believing something that “damages trust.” That is entirely subjective relative to the one whose trust was damaged.
Society has claimed heresy to suppress political and religious opponents since the beginning of human history. We have also shown a track record of being very wrong with regard to how we define heresy in the past.
Why should we believe that we are any better than our ancestors on this front?
“The thearubigins in brewed tea are highly coloured (red-brown) molecules that change according to the acidity of the liquid used.
If the water used for the tea infusion is relatively alkaline (for example, due to limescale found in “hard” water), the colour of the tea will be darker and deeper.
However, once an acid such as a slice of lemon or lemon juice is added, tea changes colour because of an increase in acidity (reduction in pH) of the beverage itself. Lemon juice is quite strong as a food acid – a few drops are enough to alter the theaurbigins, resulting in a dramatic change in colour. Interestingly, theaflavins are not that affected by the change in acidity, and still retain their normal dark red colour.”
