The issue has again arisen after City striker Mario Balotelli was allegedly subjected to monkey chants during Thursday's Europa League win at Porto on Thursday.
That came less than a week after Richards himself reluctantly closed his account on Twitter after receiving abusive messages via the social networking site.
English football has also been overshadowed by two other high-profile cases concerning alleged racism this season, involving Luis Suarez and John Terry, who denies abusing Anton Ferdinand.
Yet despite the publicity surrounding these matters, Richards does not feel there is a big problem in the country.
The 23-year-old right-back said: "It's difficult for me to comment.
"There are always going to be people who have a certain opinion of people.
"I have to say in English football that I think it has been outstanding.
"There have been a couple of cases of late we're not really happy about but since I've been playing, since I was 17, I've not really heard too much racism at all.
"There are going to be little incidents, but as long as they are sorted out and dealt with in the right manner, we've just got to move forward."
Lincolnshire Police opened an investigation last November after Richards received one abusive tweet.
He considered closing his account then but only did so after further recent incidents.
Richards said: "I did enjoy Twitter and the banter with the fans, but I didn't like the abuse you get on it.
"Sometimes you want to retaliate, but you have to be the bigger man and not.
"I thought it was just for the best for myself because it can affect your confidence if people are saying things about you.
"I just thought it was best to come off and concentrate fully on football."
City lodged an official complaint after the alleged chanting at Balotelli, which was most apparent as the Italian was substituted with 12 minutes remaining at the Estadio do Dragao.
UEFA have said they are awaiting their delegate's report - which can take up to two days to arrive after a game - before deciding on what action to take.
Richards did not hear the abuse but was pleased Balotelli, in his first match after a four-game domestic ban, gave a strong performance in the 2-1 win without rising to any provocation.
He said: "I didn't hear anything. It's not what we want to hear.
"Unfortunately, it's part and parcel of football. If people are going to do that, it's up to them.
"We will just get on with our job. It's not nice to hear and we can't do anything about it as players.
"It was just great for Mario that he played a big part in the first goal. It's nice to have him back after his suspension.
"He's become a key part of the team. A lot of people don't really talk about what he does on the field as much as they should.
"We know he's a massive player for us and he showed that."
