Nobody's is preventing anybody from speaking about anything. The jump from "too many gays on Coronation Street" to "its like Hitler's Germany and free speech is in danger" is just too much to take seriously.
Absolutely this. I am sick of hearing that we 'aren't allowed' to say whatever it is. We are. We have free speech in this country, so long as it doesn't contravene laws against slander, libel, terrorism or hate speech.
The same applies to 'I'm scared to speak out about' whatever. Again, we can speak about whatever we like, but equally, we can disagree with views we find offensive - it's called discussion.
If someone has views that would break laws if they were expressed publicly, or if they are so offensive to others that they will cause public disagreement, maybe they should re-examine those views? If they feel that they are unable to defend their POV in discussion, then again, maybe the views are indefensible.
As for Corrie, as others have said, it is unrealistic in many ways. As it's been running for 60 years and is aired for 3 hours a week, it would be very difficult to come up with something new every episode. Also, drama is about 'suspension of disbelief', as watching film of life in most streets would be very boring.
Life in Doodledog Towers is pleasant enough, but who wants to watch the Dogs getting up, pottering about a bit, me working from home some days, Mr Dog going about his day, us reading books, a bit of telly in the evening, then going back to bed? Just reading that is boring, never mind watching it in 'real time'. Spice it up with one of us going to jail for a game of pool with the neighbours, being run over by a speeding car on Accident Corner, or one of our children getting involved in an adulterous triangle and already it's got more viewing potential.
The gay footballer story seems to me a bit forced given the timing, but as a story it's got a bit more 'legs' than the usual 'coming out' ones, as that is less of a big deal than before. Soaps do give people a chance to discuss things at a remove, so if a troubled teenager or young adult is struggling to speak to their parents about their sexuality, a gay storyline might be the impetus they need. From my own perspective the gay storylines are just love stories (or not, as the case may be), the same as heterosexual ones.
