There are many things I find offensive, these include the current government, the current government's opposition, the Royal Family, the regressive anti-women laws in USA that are trying to get traction in the UK, the state of the NHS, the state of education, tax avoidance, cutting flowers for display purposes, football, influencers...I could probably list tonnes more if I was inclined.
Some entirely rational, some just oddities mostly just my opinion - however the whole point of a country where people are free to debate is that we can discuss them. Forums like this actually allow a fairly unbiased conversation to take place.
Unless divulged you wouldn't know my sex, skin colour, weight, eye colour, hair colour, if I'm disabled, my religion, my financial status. I could enter a discussion without any unconscious bias about who I am undermining what I'm trying to say.
Talk about why you think something is good/bad and have facts to support your position - don't cancel voices that disagree with you but respond with strength. If you can't do that your position and opinion is about as substantial as a sandcastle at high tide.
